Source directory for the maven-apt-plugin plugin

[Stephane-3]

I'm trying to use a plugin that should generate some source code.

But when I run the Maven build with the mvn generate-sources command, it
gives the following error:

[ERROR] Failed to execute goal
com.mysema.maven:maven-apt-plugin:1.0.4:process (default) on project
learnintouch: basedir
/home/stephane/dev/java/projects/learnintouch/src/main/java does not exist

Here is the plugin configuration:

<plugin>
<groupId>com.mysema.maven</groupId>
<artifactId>maven-apt-plugin</artifactId>
<version>1.0.4</version>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>process</goal>
</goals>
<configuration>

<processor>com.mysema.query.apt.jpa.JPAAnnotationProcessor</processor>
</configuration>
</execution>
</executions>
</plugin>

My parent project sits in the /home/stephane/dev/java/projects/learnintouch
directory.

There is only one child module, in the
/home/stephane/dev/java/projects/learnintouch/core directory.

The two pom.xml files are:

/home/stephane/dev/java/projects/learnintouch/pom.xml
/home/stephane/dev/java/projects/learnintouch/core/pom.xml

The plugin configuration is sitting the
/home/stephane/dev/java/projects/learnintouch/pom.xml file.

I'm then trying to specify a source directory, with the following:

<sourceDirectory>${basedir}/core/src/main/java/com/thalasoft/learnintouch/core/jpa/domain</sourceDirectory>

But it gives the error:

[ERROR] Failed to execute goal
com.mysema.maven:maven-apt-plugin:1.0.4:process (default) on project
learnintouch-core: basedir
/home/stephane/dev/java/projects/learnintouch/core/core/src/main/java/com/thalasoft/learnintouch/core/jpa/domain
does not exist

We can see in the above error the core/core/ doubling of the directory name.

If I then remove the core/ directory from the configuration as in:

<sourceDirectory>${basedir}/src/main/java/com/thalasoft/learnintouch/core/jpa/domain</sourceDirectory>

[ERROR] Failed to execute goal
com.mysema.maven:maven-apt-plugin:1.0.4:process (default) on project
learnintouch-core: basedir
/home/stephane/dev/java/projects/learnintouch/core/core/src/main/java/com/thalasoft/learnintouch/core/jpa/domain
does not exist

then, not one core/ directory, but two core/core/ directories are removed
in the error message.

Puzzling...

Hi,

this plugin is not written by the Maven team.
Either contact the developer of this plugin or try the apt-maven-plugin
from the Mojo team[1]

Why do you define sourceDirectory? Its default value is already
${basedir}/src/main/java

Hello,

Yes, but then my source directory is not found, because it sits in the core/ child module as I explained in my original post.

Kind Regards,

Stephane

OK, I think I misread your first message.
So, it seems you're trying to run the plugin from the parent to access
sources from a child module.

If so, then you should know it's a bad idea. Modules should generally be
independent in their execution.
If that plugin is needed in your core module, then configure it just in
that plugin.

Here, the first error is related to the fact the plugin is trying to
execute for the parent pom, but there's logically no sources. So the
execution stops there.
Then I think the second one is the core module execution inheriting the
parent configuration, but for this module ${basedir} is already containing
core, so there's core twice.

Cheers

Thanks Baptiste, I got it. Also, my initial post was a bit inaccurate as it
lacked the <outputDirectory>target/generated-sources</outputDirectory>
element.

The following plugin

<plugin>
<groupId>com.mysema.maven</groupId>
<artifactId>maven-apt-plugin</artifactId>
<version>1.0.4</version>
<executions>
<execution>
<phase>generate-sources</phase>
<goals>
<goal>process</goal>
</goals>
<configuration>
<outputDirectory>target/generated-sources</outputDirectory>

<processor>com.mysema.query.apt.jpa.JPAAnnotationProcessor</processor>
</configuration>
</execution>
</executions>
</plugin>

in the child module pom.xml file does the job now.

Cheers,
