There is indeed no /bin/include/relations-java.jar, the include folder instead contains a copy of the all the folders in the root.

The .classpath is missing, and the maven dependencies are missing.

Maven > Update Project doesn't do anything (it updates the classpath and dependencies in the working version).


On 29 March 2016 at 11:43 Daco Harkes commented:

The cause was a broken parent POM, which was in turn created by missing repositories.

The repositories can be found here: http://spoofax.readthedocs.org/en/latest/source/dev/maven.html?highlight=maven#advanced-project-pom-file .

The repositories need to be part of the POM for Maven2Eclipse. For the command-line Maven build the repositories can be part of .mvn/settings.xml, but not for M2E.

Issue can be closed.

The repositories are back in the generated POM file for the new project wizard as well.
