Usage question - automatically add target/generated-sources/java folder

[paulvi]

I have followed https://github.com/querydsl/apt-maven-plugin/wiki/m2e-usage mvn package build passed, with sources generated

but I have to manually add classpathentry in Eclipse

<classpathentry kind="src" path="target/generated-sources/java"/>

Should this target/generated-sources/java folder automatically be added in Eclipse on import?

I guess some extra pom.xml configuration is needed.

It's been a while since I used Eclipse, but doesn't the Maven Eclipse plugin solve that? mvn eclipse:eclipse?

mvn eclipse:eclipse does not generate correct eclipse files for current m2e plugin.

Usage of mvn eclipse:eclipse has been discouraged for several years now.

I think it is similar to gradle build eclipse generate Eclipse files as general project, that may be OK for a look but not for work. Anyways, I feel there should be extra things in pom.xml like maven-helper-plugin

It works.
