IDE for java can't see JAVA_HOME

ldpsanchez

I am trying to configure the IDEs for java, none can find java_home for some reason, wanted to use vscode for easy use, couldn't find java_home either

CorvusRuber

The docs did something wrong to you, son ?

ldpsanchez

CorvusRuber Excuse me, what's wrong with my question? The documentation says almost nothing, it says what I already knew and what I do in other distributions, however, in Solus, the IDE does not detect the JAVA_HOME variable which is still in the BASH variable, they do not, I do not understand why

CorvusRuber

You did this, too ?

Once a Java version has been installed, you might notice that running jar files in the terminal via java -jar foo.jar doesn’t work. This is because Solus uses a stateless configuration for its Java packages so as to avoid conflicts between different installed versions, and thus there is no java command on the PATH by default. To amend this, there are multiple possible solutions, each of which should be used for certain scenarios.

Create a .desktop file and specify env JAVA_HOME=/path/to/jdk in Exec (best for GUIs)

Create a script that sets JAVA_HOME before running the application

Symlink the java executable from within /path/to/jdk/bin into /usr/bin

Add /path/to/jdk/bin to your PATH

Apart from that, of which IDE are we talking about ? Eclipse, Netbeans, Idea, VSCode, JDeveloper, the list is fairly long....

CorvusRuber first use vscode because the program is a simple test that I need for a specific system, then I tried with eclipse, netbeans, intellij, none worked, I think it is due to the privileges to access the executable. That is my java_home
#Java home export JAVA_HOME="/usr/lib64/openjdk-11" export PATH="$JAVA_HOME/bin:$PATH"

ldpsanchez IntelliJ works fine when you configure a JDK for the project to use. It only looks at JAVA_HOME when starting to decide which Java to use for the GUI. If other IDEs are scanning for JAVA_HOME, you need to log out and back in for bashrc to propagate to running processes.

DataDrake not really, configure java_home in my session, only for my user, not for the whole system, that is, use ~ / .bashrc, I restart the system and even the other programs still do not recognize JAVA_HOME. I am following your instructions, I have read the other threads where other people mess with the general variables of the system, and you indicated that it is not correct to do that because in future updates it could corrupt the system

ldpsanchez Our docs indicate what is likely to work for Java applications not IDEs. Not everything in the universe reads JAVA_HOME to look for a JDK. Many things are hard-coded to look in specific paths or to use vendored JDKs, others like IntelliJ ignore JAVA_HOME entirely for project JDKs because they assume it will be configured incorrectly. You cannot rely on that always working.

If JAVA_HOME isn't working for your IDE of choice, then the thing to do would be to find out how to configure a specific JDK within a project for that IDE.

That depends entirely on what environment variables they are messing with. Generally speaking, setting JAVA_HOME is harmless on Solus because all of our packaged Java software is already configured to use a specific JDK. That's not to say that it won't affect other third party applications.

DataDrake I understand, that's why I went to investigate in the documentation of vscode, eclipse and intellij. In vscode, even if I manually configure the jdk path, it still cannot recognize it, in eclipse it changes and indicates that it does not have permissions, the same happens with intellij. I did all this long before I came to ask for help in the forum, because, really, I no longer understand what the fault is, because they cannot find the variable to use the jdk. am I wrong with setting java_home in .bashrc?

DataDrake

ldpsanchez I find it hard to believe that IntelliJ isn't working, seeing as how I was able to add JDK 11 and create a new project with it.

I have difficulty setting it on Vscode
