gradlew command not found? - java

I am working on a Java project with Gradle Wrapper (gradlew). I use Ubuntu Linux as my OS. When I run "gradle" it runs, and gives me information. But when I run "gradlew", it outputs as:
No command 'gradlew' found, did you mean:
Command 'gradle' from package 'gradle' (universe)
gradlew: command not found"
I did my research, I have the JDK, and I did sudo apt-get install gradle. How can I fix it?
The error is:
gradlew clean jpackage
Output:
bash: gradlew: command not found...

Linux and macOS
As noted in the comments, just running
./gradlew
worked for me. Adding the ./ tells it to look in the current directory since it isn't in the path.
Windows PowerShell
.\gradlew

The Gradle wrapper needs to be built. Try running gradle wrapper --gradle-version 2.13.
Remember to change 2.13 to your Gradle version number. After running this command, you should see new scripts added to your project folder. You should be able to run the wrapper with ./gradlew build to build your code.
Please refer to this guide for more information: Building Java Projects with Gradle

Running this Bash command works for me by running chmod 755 gradlew as sometimes file properties changed upon moving from one OS to another (Windows, Linux and Mac).

If you are using Mac, try giving root access to gradlew by doing:
chmod +x ./gradlew

From Mac,
Nothing is working except the following command:
chmod 777 gradlew
Then
./gradlew

The same problem occurs to me...
I check the file wrx permissions with:
$ls -l ./gradlew -> -rw-rw-r-- (no execute permission)
So I use command $chmod +x ./gradlew and this problem is solved.

In addition to Suragch's answer:
Linux and macOS
./gradlew clean
Windows PowerShell
.\gradlew clean
Windows cmd
gradlew clean

You must have the Gradle wrapper available locally before using gradlew. To construct that
gradle wrapper # --gradle-version v.xy
Optionally, pass the Gradle version explicitly. This step produces the gradlew binary. And then you should be able to
./gradlew build

For Ubuntu (Linux) users:
Doing bash ./gradlew build works, but ./gradlew build does not work.
For me, the issue was it was on the NTFS file system, and Linux does not let you execute a script from NTFS.
Try moving the code from NTFS to a Linux partition. Then ./gradlew build should work.

If you are using Visual Studio Code with Flutter, you should find it in your app folder, under the android folder:
C:\myappFolder\android
You can run this in the terminal:
./gradlew signingReport

The first thing is you need to run the gradle task that you mentioned for this wrapper. Example:
gradle wrapper
After running this command, check your directory for the gradlew and gradlew.bat files. gradlew is the shell script file, and it can be used in Linux and macOS. gradlew.bat is the batch file for the Windows OS. Then run,
./gradlew build (Linux and Mac). It will work.

Issue: Couldn't find gradlew at path jenkins
In my case, within the Jenkins CI for flutter project, I have to first run the flutter build app command, and then it automatically generated a gradlew file. And the above issue is resolved.
I put this command in my Jenkins file:
flutter build apk

In a Flutter project, don't forget to go to 'android' folder with 'cd android'.
Then you can run a command like './gradlew build' or './gradlew clean' on it (macOS).

If the answer marked as correct does not work, it is because you need to identify yourself as a super user.
sudo gradle wrapper --gradle-version 2.13
It worked for me.

I faced the same issue, but after some tries I found
it was happening because I was trying to create build in Git Bash,
instead of CMD with system administrator access.
If you create build with a command prompt, run as administrator. Then the build will get created.

If you are trying to run this command for a Flutter app, then go to the android folder first by cd android. And then use the command, and it should work.
cd android
./gradlew signingReport

I use IntelliJ IDEA and in Windows in the terminal I type:
gradlew.bat run
It is working for me.

Instead of gradlew assembleRelease, use ./gradlew assembleRelease.

I had to do dos2unix * in my current folder to make it work.

Ubuntu
Error:
Command 'gradlew' not found, did you mean:
command 'gradle' from snap gradle (7.2)
command 'gradle' from deb gradle (4.4.1-13)
See 'snap info ' for additional versions.
Use this command:
./gradlew signingReport

Install rust on openjdk docker image

I'm trying to write a dockerfile to run a rust test suite that requires a jar to be running on a separate port. I've downloaded the jar into the project and would like to start with the openjdk docker image and download rust as well. That way I can use the java command to run the jar then cargo to run the tests.
# Start with java
FROM openjdk:latest
# Add rust
RUN <one line command to download rust>
# Install production dependencies and build a release artifact.
RUN cargo build --release
# Start chromedriver, geckodriver, and selenium standalone binary
RUN ./thirtyfour/tests/binaries_and_jars/chromedriver
RUN ./thirtyfour/tests/binaries_and_jars/geckodriver
RUN java -jar ./thirtyfour/tests/binaries_and_jars/selenium.jar standalone --port 1234
# Run the tests
RUN cargo test
I was hoping to download rust using the curl command provided on the website, passing all the options as cli arguments, but I still get the prompt. Running
curl https://sh.rustup.rs -sSf | sh -s -- --default-toolchain stable --default-host x86_64-unknown-linux-gnu --profile default
still produces the confirmation prompt.
I'm open to any solution here, including
A one-line command to install rust
Starting from the rust image + a one-line command to install java.
You can skip the confirmation prompt by adding the -y argument. This can be found in the help page of installer script.

USAGE:
rustup-init [FLAGS] [OPTIONS]
FLAGS:
-v, --verbose Enable verbose output

UnsupportedOperationException: No format processor for org.jboss...MavenResolvedArtifact was found

I'm creating an application to automatically generate resources for a launcher, this requires automatically resolving maven dependencies, but I'm getting an UnsupportedOperationException while running JBoss Shrinkwrap Resolver
I'm running this inside a docker container, to avoid the local repository caching, it works outside of the container on the host, but I'm unsure what is missing inside the container.
My resolver config is a simple example, converting to a MavenResolvedArtifact
MavenResolvedArtifact[] artifacts = Maven.configureResolver()
.withMavenCentralRepo(true)
.withRemoteRepo("internal-nexus", MAVEN_URL, "default")
.resolve("com.company:application:" + PROJECT_VERSION)
.withTransitivity()
.asResolvedArtifact();
My Dockerfile is also relatively simple, using openjdk9, including the bootstrapper program, a shell script and some environment variables.
FROM openjdk:9
COPY bootstrapper-shaded.jar /bootstrapper.jar
COPY docker-run.sh /run.sh
ENV CLONE_URL https://github.com/company/repository.git
ENV NEXUS_BASE https://nexus.company.com/
ENV NEXUS_REPO repository
RUN chmod +x /run.sh
RUN apt-get update && apt-get install -y git software-properties-common maven
ENTRYPOINT ["/run.sh"]
And the run.sh script copies some files (removed for brevity), runs the build, then the bootstrapper
#!/bin/sh
rm -rf /boostrap/*
cd /bootstrap/
git clone $CLONE_URL work
cd work
chmod +x ./gradlew
./gradlew clean build
NEXUS_URL=`printf $NEXUS_BASE; printf "/repository/"; printf $NEXUS_REPO` ./gradlew upload
java -jar /bootstrapper.jar 0
I expect the output to be the same as on the host machine, an array of MavenResolvedArtifacts, however the following exception is thrown on the final line of the code snippet, .asResolvedArtifact()
Exception in thread "main" java.lang.UnsupportedOperationException: No format processor for org.jboss.shrinkwrap.resolver.api.maven.MavenResolvedArtifact was found. Supported processors are: class org.jboss.shrinkwrap.resolver.impl.maven.archive.ArchiveFormatProcessor

at com.company.ResolveTask.run(ResolveTask.java:39)
at com.company.Bootstrapper.main(Bootstrapper.java:102)
Apologies for any typos in the stacktrace, VM wouldn't let me copy-paste out of it so I had to type it out myself.
Update: Haven't found anything else on google yet, have tried clean builds to no avail.
You need to change the type of artifacts to
org.jboss.shrinkwrap.resolver.impl.maven.archive.ArchiveFormatProcessor
or at least cast it to that when you declare.

CAN'T Build Apache spark with MAVEN

I have downloaded Apache spark and trying to build it with MAVEN as suggested here. http://spark.apache.org/docs/1.0.0/building-with-maven.html
But I am not able to resolve the error after running the command -
build/mvn -DskipTests clean package run , the error is- build/mvn: No such file or directory .
I checked by running mvn -v and also JAVA_HOME is set to the JDK.(screen shot attached ) .
Please help to resolve the problem.command promt output
mvn -DskipTests clean package run
You don't need to use build/mvn. I am assuming you have mvn installed somewhere within the system.

How to install Intellij IDEA on Ubuntu?

I'm new to Ubuntu and Linux in general. I want to code in Java on my computer, but I'm having problems installing IntelliJ IDEA on Ubuntu. I have downloaded and extracted the file and for some reason renamed the folder to idea. I tried moving the folder to /usr/share/applications or something but I didn't have permission. I used sudo -i in terminal to gain permission but didn't manage to get out of root folder. Can anyone help me with a step by step way to move the folder, create a shortcut in the search bar or whatever it's called and install it properly?
Note: This answer covers the installation of IntelliJ IDEA. For an extended script, that covers more JetBrains IDEs, as well as help for font rendering issues, please see this link provided by brendan.
Furthermore, a manual Desktop Entry creation is optional, as newer versions of IntelliJ offer to create it on first startup.
I have my intellij int /opt folder. So what I do is:
Download Intellij
Extract intellij to /opt-folder: sudo tar -xvf <intellij.tar> -C /opt/ (the -C option extracts the tar to the folder /opt/)
Create a Desktop Entry File called idea.desktop (see example file below) and store it anywhere you want (let's assume in your home directory)
Move the idea.desktop from your home directory to /usr/share/applications: sudo mv ~/idea.desktop /usr/share/applications/
Now (in a lot) Ubuntu versions you can start the application after the GUI is restarted. If you don't know how to do that, you can restart your PC..
idea.desktop (this is for community edition version 14.1.2, you have to change the paths in Exec= and Icon= lines if the path is different for you):
[Desktop Entry]
Encoding=UTF-8
Name=IntelliJ IDEA
Comment=IntelliJ IDEA
Exec=/opt/ideaIC-14.1.2/bin/idea.sh
Icon=/opt/ideaIC-14.1.2/bin/idea.png
Terminal=false
StartupNotify=true
Type=Application
Edit
I also found a shell script that does this for you, here. The given script in the link installs Oracle Java 7 for you and gives you the choice between Community and Ultimate Edition. It then automatically downloads the newest version for you, extracts it and creates a desktop entry.
I have modified the scripts to fulfill my needs. It does not install java 8 and it does not ask you for the version you want to install (but the version is kept in a variable to easily change that). You can also update Intellij with it. But then you have to (so far) manually remove the old folder! This is what i got:
Edit2
Here is the new version of the script. As mentioned in the comments, breandan has updated the script to be more stable (the jetbrains website changed its behavior). Thanks for the update, breandan.

You can also try my ubuntu repository: https://launchpad.net/~mmk2410/+archive/ubuntu/intellij-idea
To use it just run the following commands:
sudo apt-add-repository ppa:mmk2410/intellij-idea
sudo apt-get update
The community edition can then installed with
sudo apt-get install intellij-idea-community
and the ultimate edition with
sudo apt-get install intellij-idea-ultimate
JetBrains has a new application called the Toolbox App which quickly and easily installs any JetBrains software you want, assuming you have the license. It also manages your login once to apply across all JetBrains software, a very useful feature.
To use it, download the tar.gz file here, then extract it and run the included executable jetbrains-toolbox. Then sign in, and press install next to IntelliJ IDEA:
If you want to move the executable to /usr/bin/ feel free, however it works fine out of the box wherever you extract it to.
This will also make the appropriate desktop entries upon install.
Since Ubuntu 18.04 installing Intellij IDEA is easy! You just need to search "IDEA" in Software Center. Also you're able to choose a branch to install (I use EAP).
For earlier versions:
According to this (snap) and this (umake) articles the most comfortable ways are:
to use snap-packages (since versions IDEA 2017.3 & Ubuntu 14.04):
install snapd system. Since Ubuntu 16.04 you already have it.
install IDEA snap-package or even EAP build
to use ubuntu-make
(for Ubuntu versions earlier than 16.04 use apt-get command instead apt):
Add PPA ubuntu-desktop/ubuntu-make (if you install ubuntu-make from standard repo you'll see only a few IDE's):
$ sudo add-apt-repository ppa:ubuntu-desktop/ubuntu-make
Install ubuntu-make:
$ sudo apt update
$ sudo apt install ubuntu-make
install preffered ide (IDEA, for this question):
$ umake ide idea
or even ultimate version if you need:
$ umake ide idea-ultimate
I upgrade Intellij IDEA via reinstalling it:
$ umake -r ide idea-ultimate
$ umake ide idea-ultimate
TL;DR:
Download IntelliJ IDEA from here.
cd Downloads
extract the downloaded file: sudo tar xf ideaIC-2017.2.5.tar.gz -C /opt/
Switch to the bin directory: cd /opt/idea-IC-172.4343.14/bin
Run idea.sh from the bin subdirectory.
Since Ubuntu 16.04 includes snapd by default.
So, the easiest way to install the stable version is
IntelliJ IDEA Community:
$ sudo snap install intellij-idea-community --classic
IntelliJ IDEA Ultimate:
$ sudo snap install intellij-idea-ultimate --classic
For the latest version use channel --edge
$ sudo snap install intellij-idea-community --classic --edge
Here is the list of all channels https://snapcraft.io/intellij-idea-ultimate (drop down 'All versions').
options
--classic
The --classic option is required because the IntelliJ IDEA snap requires full access to the system, like a traditionally packaged application.
[https://www.jetbrains.com/help/idea/install-and-set-up-product.html#install-on-linux-with-snaps]
--edge
--edge Install from the edge channel
[http://manpages.ubuntu.com/manpages/bionic/man1/snap.1.html]
Note: Snap, also work a few major distributions: Arch, Debian, Fedora, openSUSE, Linux Mint,...
Recent IntelliJ versions allows automatic creation of desktop entry. See this gist
Launch from commandline. If launching for the first time, setup will ask about creating a desktop launcher icon; say yes. Or else after launching (ie. from the commandline) any time, use the IDEA menu Configure > Create Desktop Entry . That should create /usr/share/applications/intellij-idea-community.desktop
Trigger the Ubuntu desktop search (ie. Windows key), find the Intellij IDEA you used to create the desktop entry.
Drag the icon it's showing into the Ubuntu Launcher.
In a simple manner you can also try to just run a pre-packaged docker with intellij, I found the good job of #dlsniper : https://hub.docker.com/r/dlsniper/docker-intellij/
you just need to have docker installed and to run :
docker run -tdi \
--net="host" \
--privileged=true \
-e DISPLAY=${DISPLAY} \
-v /tmp/.X11-unix:/tmp/.X11-unix \
-v ${HOME}/.IdeaIC2016.1_docker:/home/developer/.IdeaIC2016.1 \
-v ${GOPATH}:/home/developer/go \
dlsniper/docker-intellij
Standalone installation
Download the tarball.tar.gz.
Extract the tarball to a directory that supports file execution.
For example, to extract it to the recommended /opt directory, run the following command:
sudo tar -xzf ideaIC-2020.3.tar.gz -C /opt
Go to /opt folder and open intellij folder
Go to /bin folder and execute the command sh idea.sh
Now the application opened and create the desktop shortcut if you need
I find and follow this youtube:
https://www.youtube.com/watch?v=PbW-doAiAvI
Basically, download the tar.gz package, extract into /opt/, and then run the "idea.sh" under bin folder (i.e. /opt/idea-IC-163.7743.44/bin/idea.sh)
Enjoy
I needed to install various JetBrains tools on a number of machines from CLI, so I wrote a tiny tool to help with that. It also uses cleaner APIs from JB making it hopefully more stable, and works for various JB tools.

Install IntelliJ on Ubuntu using Ubuntu Make
You need to install Ubuntu Make first. If you are using Ubuntu 16.04, 18.04 or a higher version, you can install Ubuntu Make using the command below:
sudo apt install ubuntu-make
Once you have Ubuntu Make installed, you can use the command below to install IntelliJ IDEA Community edition:
umake ide idea
To install the IntelliJ IDEA Ultimate edition, use the command below:
umake ide idea-ultimate
To remove IntelliJ IDEA installed via Ubuntu Make, use the command below for your respective versions:

Maven error while assembling hadoop in stand alone mode

I am new to hadoop and maven. I will like to compile the hadoop 2.0.3 from the source and install it. I am following instructions from
http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/SingleCluster.html
So far, i have managed to download hadoop source code and from the source directory issued "mvn clean install -Pnative"
Next i tried to execute mvn assembly:assembly, but i get following error:
Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.3:assembly (default-cli) on project hadoop-main: Error reading assemblies: No assembly descriptors found. -> [Help 1]
Please help so that i can move forward.
Also, the above mentioned install link, does not mention what should be the value of "$HADOOP_COMMON_HOME/$HADOOP_HDFS_HOME"
I compiled 1.0.4 just as an academic exercise. Not sure if it will be valid for 2.0.3
This should be done (on Ubuntu) before you start compilation to make sure that all needed stuff is there:
sudo apt-get -y install maven build-essential protobuf-compiler autoconf automake libtool cmake zlib1g-dev pkg-config libssl-dev
I did not had subversion so I did this too:
sudo apt-get install subversion
After that I checked out the code:
svn checkout http://svn.apache.org/repos/asf/hadoop/common/tags/release-1.0.4/ hadoop-common-1.0.4
Then went to newly created folder “hadoop-common-1.0.4″ and gave command:
ant clean package
You can refer to my blog for the whole story:
