xtext-maven-plugin overwriting output configuration [message #1469487]

Hi,
I'm not sure what I do wrong and maybe the solution is quite easy.
As also described in this thread, I am trying to use the xtext-maven-plugin but it does not write to another folder.

What I try to do is generate Java code standalone from maven and it works using the xtext-maven-plugin.

...
<outputConfigurations>
    <outputConfiguration>
        <outputDirectory>${project.basedir}/src-gen</outputDirectory>
    </outputConfiguration>
<outputConfigurations>
...

All that happens is the code is updating in "target/xtext-temp/<and so on>", the default location.

Does anybody know how to fix that? I use version 2.6.2 of the xtext-maven-plugin.

Regards,
Steffen

Hi

from what I know the target/xtext-temp contains the temporary stub Java
classes, the actual generated code should go into the directory you
specified... does src-gen contain anything?

cheers
Lorenzo

No, src-gen is empty and not even affected by the maven install, regarding to the timestamp.
I also tried the solutions in the thread I linked in my first post, but it didn't help anything.

greetings, Steffen

I had a look at it several times now and it's a great example! That's why I do not understand why it is still not working.

I will post my pom.xml here now and hope that it was just a dumb little mistake I made:

The (relevant) maven output I get on mvn install:
...
[INFO] --- xtext-maven-plugin:2.6.2:generate (default) @ Student ---
[INFO] Encoding: not set. Encoding provider will be used.
[INFO] Compiler source level: 1.5

And scr-gen is empty in the end

It seems like, yes.
According to https://bugs.eclipse.org/bugs/show_bug.cgi?id=410736, you already worked on that, if you are the same Christian Dietrich. In this post there also is an attachment in one of the answers that shows a solution that seems to work. But when I use the configuration in my project, it doesn't...
