Maven Dependencies in Module Path in Runconfiguration [message #1800143]

I'm currently in the process of creating my first Java 10 (soon to be 11) Module based project.

The Problem is, I also chose Maven for dependency managment and I need these dependencies to be on the module path.
I managed to to this for the build configuration by simply dragging the "Maven Dependencies" into the module path. But the same does not seem to be possible for any run configurations. These list "Maven managed dependencies" on the classpath resulting in a java.lang.module.FindException when trying to run them.

The Project itself can be successfully build using eclipse and/or maven. Also using the experimental maven-jlink-plugin results in a working runtime image.

It seems to me all that would be needed to fix this, is to have the maven managed dependencies on the module path inside the run configuration. But as I said, I could not find any way to do this.

Hello,

I will put some pictures of my setup for java 11 using java FX I hope it will be helpful.

my POM:
index.php/fa/34533/0/

I also created module-info.java:
index.php/fa/34534/0/

the file created looks like this:
index.php/fa/34535/0/

My build path looks like this (done automatically):
index.php/fa/34537/0/

Now you can create a regular run configuration and also export executable jar

Regards.

The "transitive" was added manually because the compiler was not happy.... ;-)

I've done pretty much the same thing, which works for building:
index.php/fa/34540/0/

But when creating a regular run configuration, the maven dependencies end up in the class path with seemingly no way to change that:
index.php/fa/34541/0/

Hi,

This what I have in the run configuration (looks like yours)

But if hit the "show command line" we can see that the command line include -p

index.php/fa/34543/0/

which stands for:

--module-path modulepath... or -p modulepath (from https://docs.oracle.com/en/java/javase/11/tools/tools-and-command-reference.html )

Looks like a discrepancy between run configuration dialog and the java build path dialog or am I missing something...

Do you have module-info.java ?

I do have a module-info.
But when I click show command line, the maven dependencies are listed only as -classpath, manually executing the command with them moved to -p works.

edit: But I just noticed another thing. While "Maven Dependencies" itself is listed as "Is modular" in the build path settings, the actual dependencies themselves are listed as "Is not modular - non modifiable". But the dependencies are clearly modular as they contain module-info.class and are usable when building with maven/jlink directly.

Really, I spent two days trying to get this running, fixing almost all problems.
And it all is allready fixed, simply by updating from 2018-09 to 2018-12.
I feel really stupid now.

Dear André,

I have been a programmer since 1973...(I am retired now).

Just to let you know that you will fill stupid many more times.

Do not let it make you feel bad about yourself.

Simply look at it as a lesson and in the future try to remember the lesson.

And always be lazy...

Regards.
