I'm new to linux, I don't understand symbolic links, how apt-get works or how to get back removed files. Almost all commands here are from searching for a solution to the problem.
When I run update-java-alternatives -l I get
java-1.11.0-openjdk-amd64 1111 /usr/lib/jvm/java-1.11.0-openjdk-amd64
java-1.17.0-openjdk-amd64 1711 /usr/lib/jvm/java-1.17.0-openjdk-amd64
But when I attempt to do ls or cd to /usr/lib/jvm/java-1.17.0-openjdk-amd64 I get the error that it doesn't exist.
While I was trying some things I removed the directory, and now I can't get it back, don't know what to install and is not in the recycle bin. Attempted the following commands
sudo apt-get install openjdk-17-jdk // already installed
sudo apt-get install openjdk-17-jre // already installed
I need to get the directory to select it as the home folder for IntelliJ IDEA JRE and be able to run a Spring Boot >6.0 application, since java 11 needs Spring Boot 5.3.
ls /usr/lib/jvm/ returns
default-java java-1.11.0-openjdk-amd64 java-11-openjdk-amd64 java-17-openjdk-amd64 openjdk-17
As you can see I have the directory java-1.11.0-openjdk-amd64 which works fine when selecting it as home directory in the Intellij IDE, but I need the java-1.17
Also did this with JAVA_HOME and attempted sudo apt-get install java-1.17.0-openjdk-devel but no package found.
I'm trying to install lombok in the Spring Tool Suite 4 ide which is in the /opt folder on Ubuntu. The command: java -jar lombok.jar does not work because the opt folder requires privileges.
I tried using the command suggested by the installation software: sudo java -jar lombok.jar I get the result:
sudo: java: command not found
Note: I have the SDKMAN software development kit manager installed to manage java versions.
Because root does not have sdkman install. root can not get java.
You can do this:
sudo su -
mkdir -p /usr/lib/jvm
cd /usr/lib/jvm
ln -s /home/YourUserName/.sdkman/candidates/java/current jdk
nano /root/.bashrc
# ADD This
export JAVA_HOME=/usr/lib/jvm/jdk
export PATH=/usr/lib/jvm/jdk/bin:$PATH
# Ctrl + O save
# Ctrl + X exit nano
exit
UPDATE:
Add JDK Path to sudoers config:
Run Command : sudo nano /etc/sudoers
find Defaults secure_path="/usr/local/sb..."
append :/usr/lib/jvm/jdk/bin at end of this line
it will like Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin:/usr/lib/jvm/jdk/bin"
save and exit nano.
Test: sudo java -version
Then you can run sudo java -jar lombok.jar
Tesseract run successfully in eclipse, windows 7, Tomcat 8
When I run the same application on linux machine(RHEL)+java 8+tomcat 8 I get classdefnotfound error. The class is present (TessAPI.class) in classes folder.
I did this to setup in linux.

Am I missing something here?
After spending much time I successfully completed OCR integration with Red Hat linux, with all the steps above and below is additional step I have done, might be helpful for someone in near future :)
Added(created new file with name "setenv.sh" in tomcat_home/bin)
Add these lines

<-- this line as my default jre was 1.7
LD_LIBRARY_PATH=/usr/local/lib/:/usr/local/apr/lib:$CATALINA_HOME/lib
<-- /usr/local/lib location tesseract .so available
export LD_LIBRARY_PATH
I want to be able to compile and run basic java apps within the android terminal termux. I checked out Terminal IDE, but that is incompatible with Android 5.0+. Additionally, I tried to install the arm64 jdk from Oracle's website, which android fails to recognize. I am running CM 13 and to clarify, I want to be able to run commands like javac and java directly from my phone.
If you have Termux, you can download the deb file here, and install it with apt-get install /path/to/deb. A command to download and install the JRE and JDK for arm:
cd ~ # Change to home directory
apt-get install -y wget # BusyBox wget doesn't support HTTPS
hash -d wget # Forgets the BusyBox wget path so new one is used
wget https://archive.org/download/openjdk-9-jre-headless_9.2017.8.20-1_x86_64/openjdk-9-jre-headless_9.2017.8.20-1_arm.deb # Download JRE
wget https://archive.org/download/openjdk-9-jre-headless_9.2017.8.20-1_x86_64/openjdk-9-jdk-headless_9.2017.8.20-1_arm.deb # Download JDK
apt-get install -y ./openjdk-9-jre-headless_9.2017.8.20-1_arm.deb ./openjdk-9-jdk-headless_9.2017.8.20-1_arm.deb # Install the files
rm openjdk-9-*.deb # Remove the files after because they're huge
Or a one-liner to copy and paste:
cd ~ && apt-get install -y wget && hash -d wget && wget https://archive.org/download/openjdk-9-jre-headless_9.2017.8.20-1_x86_64/openjdk-9-jre-headless_9.2017.8.20-1_arm.deb && wget https://archive.org/download/openjdk-9-jre-headless_9.2017.8.20-1_x86_64/openjdk-9-jdk-headless_9.2017.8.20-1_arm.deb && apt-get install -y ./openjdk-9-jre-headless_9.2017.8.20-1_arm.deb ./openjdk-9-jdk-headless_9.2017.8.20-1_arm.deb && rm openjdk-9-*.deb
To install for another architecture, replace occurences of "arm" with the correct architecture. There are files for "arm" (most 32-bit phones), "aarch64" (ARM64/armv8, most 64-bit phones), "i686" (x86), and "x86_64". Most phones have either arm or aarch64. I believe the arm version should at least work on aarch64 (may be wrong?), so arm should work for almost everyone. But if you know what your device has, use that instead.
Edit: to find your device's architecture, run uname -m from Termux.
#moderatelygood Go to Google Play Store and download GNURoot Debian. It is a fakeroot, i.e. terminal emulator. Many other terminal emulators are available in the Play Sore, but this ine is very good. It lives at https://github.com/corbinlc/GNURootDebian and website is http://corbinlc.github.io/GNURootDebian You can download many packages like this:
apt-get update
apt-get install default-jdk
apt-get install python
and so on.
You would be able to compile/run programs in these languages. Use some text editor to write programs, like Jota Text Editor, also available in Play Store.
Actually Terminal can be used if you're only interested in javac , java, jar . That is , you can use these three on Lollipop. I am using Terminal IDE on Android 5.1.1, it works as expected. The usable version can be found at https://www.dropbox.com/s/h2d23ecbrt2akeu/terminalide-2.02-binary-mod-signed.apk?dl=0. If you want to give it a try then open this mod terminal and do : cp /system/lib/libjavacrypto.so ~/system/lib , copying this library should do the job(did for me) leaving java and dx commands working.
Java can installed on termux. INSTALLION of java on termux take very short period of time and install directly from termux-source, this program really work for me, i am dame sure it will also work for you also......
git clone https://github.com/EagleComrade/Termux-java.git
cd Termux-java
chmod +x install.sh
bash install.sh
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.
