I am facing the issue while I build the android. I installed java jdk properly.

In path variable you have to give the both JDK and JRE path upto bin,
like this
path : ....;C:\Program Files\Java\jdk1.8.0_181\bin;C:\Program Files\Java\jre1.8.0_181\bin;
coming to JAVA_HOME give the path upto JDK folder
JAVA_HOME : C:\Program Files\Java\jdk1.8.0_181
u have given upto bin may be that's the issue.
If your cmd is open then close and open new cmd and do the operations
Thank you

I am trying to run a React native app with this command

ERROR: JAVA_HOME is set to an invalid directory: C:\Program Files\Java\jdk1.8.0_202\bin
Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.
error Failed to install the app. Make sure you have the Android development environment set up: https://reactnative.dev/docs/environment-setup.
Error: Command failed: gradlew.bat app:installStagingDebug -PreactNativeDevServerPort=8081
Here is my environment path looks like
and this one
Still getting the error when I run the command.
JAVA_HOME shouldn’t point to the bin directory. It should point to the JDK installation path.
It should be: C:\Program Files\Java\jdk1.8.0_202, also you don't need JRE if you already have %JAVA_HOME%\bin, see https://www.baeldung.com/java-home-on-windows-7-8-10-mac-os-x-linux

In IntelliJ IDEA go to File>Project Structure>SDK>JDK home path. Copy it and then go to My Computer>Advanced Settings>Environment Variables Change the JAVA_HOME path to what you have copied. Then open new cmd, and try mvn -v

JAVA_HOME should point to a JDK not a JRE even though it points to a JDK [duplicate]

JAVA_HOME should point to a JDK not a JRE

Hello and thank you for any help you can provide.
I just upgraded to Ubuntu 18.04.1 and before the install my JAVA_HOME for my path was defined properly and worked successfully. However, I am now unable to use Maven due to the following error: "JAVA_HOME should point to a JDK not a JRE". I know this is a common problem and I tried a lot of potential solutions before making this post.
When I echo $JAVA_HOME, I get back /usr/lib/jvm/java-11-openjdk-amd64/bin which is what I set it to be in my .bashrc via the following lines:
JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64/bin
export JAVA_HOME
PATH=$PATH:$JAVA_HOME
export PATH
From there, I also checked Which java where I got the output of /usr/bin/java. I checked further and found that readlink -f /usr/bin/java returns a value of /usr/lib/jvm/java-11-openjdk-amd64/bin/java. Again, this points to a JDK not a JRE.
I also attempted to fix the issue by configuring a java with sudo update-alternatives --config java and chose the value of /usr/lib/jvm/java-11-openjdk-amd64/bin/java
To top it all off, I have reinstalled java and maven and I have restarted my computer and command line multiple times.
First, try and remove the /bin from your JAVA_HOME path.
You should reference the main folder of the JDK, not its bin/ subfolder.
JAVA_HOME=/usr/lib/jvm/java-11-openjdk-amd64

Ubuntu 14.04 - Oracle JDK 8 - Where is the JAVA_HOME environment variable defined? [duplicate]

Ubuntu: change the path from OpenJDK 6 to Oracle JDK 7

Closed 6 years ago.
I am trying to uninstall Oracle jdk 8 on my Ubuntu 14.04 server, in order to replace it with open jdk 8 because open source ftw. I have run apt-get purge, apt-get autoclean, logged out, logged back in, and when I run the env command, I see the following:
JAVA_HOME=/usr/lib/jvm/java-8-oracle
I do not want to overwrite this value in my .bashrc file, I do not want to take shortcuts or apply band aids, I want to fix the problem at the source by finding where it is set and removing it. Please help
I found the solution. I ran the following command to find files with the old jdk path:
sudo find / -type f -exec grep -Flm 1 '/usr/lib/jvm/java-8-oracle' {} +
The culprits were in the following directory:
/etc/profile.d

Find the java.exe location from java [duplicate]

Get path to java JRE
(3 answers)
Closed 9 years ago.
I am wondering if there is a way, from java, to find the location of the java.exe running the program?
My use case is that I am trying to have Java execute a batch script that needs JAVA_HOME to be set in the local environment. The environment that I am executing this on may not have JAVA_HOME set or even the java executable on the path, but I would assume that the JVM knows where its executable is located.
System.getProperty("java.home");
is one option. Which shows the following directory in my machine:
C:\Program Files\Java\jdk1.7.0_02\jre
Most important system properties are listed here.
The java.home property will supply the path to the currently running JRE, regardless of what is installed, or what JAVA_HOME is. See the Oracle documentation here.
System.getProperty("java.home");
