We need to doublecheck the intent here, it was just clear that there is some mishap.

Javadoc says "Resolve the executable dependencies for the specified project" while javadoc param again speaks about plugin.

Does getRemoteProjectRepositories() consider repositories declared in <repositories> in the POM?

Gson is using exec-maven-plugin to execute a JAR which is not available in Central. Previously it used <pluginRepositories> and that worked, but this broke now with exec-maven-plugin 3.6.0. However, changing the POM to use <repositories> instead does not seem to work either: google/gson#2917

Do you have an idea what could be causing this? Am I doing something wrong here?

I will check again.
@Marcono1234 please create new issue as this one is closed.

@Marcono1234 will be fixed in
