Incorrect module-path during Linux build?

[EasyG0ing1]

During an attempt to build for Linux, I received this error (I added the line breaks to make it easer to see):

Failed to execute goal io.github.fvarrui:javapackager:1.6.5:package (linux) on project GistFX: Command execution failed:
/home/michael/Java/jdk-18.0.1.1/bin/jlink 
    --module-path /home/michael/Java/jdk-18.0.1.1/jmods 
    [Ljava.lang.String;@634aa81e --add-modules ALL-MODULE-PATH 
    --output /home/michael/IdeaProjects/GistFX/target/GistFX/jre 
    --no-header-files 
    --no-man-pages
    --strip-debug 
    --compress=2 
-> [Help 1]

Here is the same output unedited

Failed to execute goal io.github.fvarrui:javapackager:1.6.5:package (linux) on project GistFX: Command execution failed: /home/michael/Java/jdk-18.0.1.1/bin/jlink --module-path /home/michael/Java/jdk-18.0.1.1/jmods [Ljava.lang.String;@71b26880 --add-modules ALL-MODULE-PATH --output /home/michael/IdeaProjects/GistFX/target/GistFX/jre --no-header-files --no-man-pages --strip-debug --compress=2 -> [Help 1]

Where I believe the problem exists, is here:

--module-path /home/michael/Java/jdk-18.0.1.1/jmods

I'm not sure where it's getting this path from but clearly my module path doesn't exist within the JDK folder tree...

Here is my POM config:

Hi @EasyG0ing1! I'm sorry for my late reply. I've been out for working.

Are you running the packaging process on Linux or Mac OS?

[fvarrui]

This path:

/home/michael/Java/jdk-18.0.1.1/jmods

comes from: jdkPath + /jmods

[EasyG0ing1]

@fvarrui - I'm running the packaging process on Ubuntu Linux ... latest version.

When I do a mvn clean package -X I get this in the output ...

Seems to be an issue with objcopy not being found - whatever that is ... I did a find for any file with that name and nothing came back so I don't know what it's looking for, nor why it's looking for that file.

[EasyG0ing1]

@fvarrui - OK, nevermind, I figured it out ... apparently objcopy is part of something called binutils ... so I installed that and everything completed successfully ... I have install artifacts ... now to go test them :-)

[fvarrui]

Hi @EasyG0ing1! Great ... sorry for my lack of help. Despite of this problem has already been reported before, I didn't realize that this could be the same case. I think I'm going to add a comment in the docs.

[fvarrui]

And there's an error when printing the executed commands (and possibly this causes confusion):

/home/michael/Java/jdk-18.0.1.1/bin/jlink 
    --module-path /home/michael/Java/jdk-18.0.1.1/jmods 
    [Ljava.lang.String;@634aa81e --add-modules ALL-MODULE-PATH 
    --output /home/michael/IdeaProjects/GistFX/target/GistFX/jre 
    --no-header-files 
    --no-man-pages
    --strip-debug 
    --compress=2 

In the third line you can see this: [Ljava.lang.String;@634aa81e .... it's only a problem when printing arrays. It doesn't affect to the command execution, but I have to fix it.

[EasyG0ing1]

@fvarrui - Yeah, I noticed that. I just deleted it before running the command independently, which was helpful in finding the source of the problem, ultimately.
