Tycho validate-version goal fails with error "OSGi version 3.10.0.SNAPSHOT must have .qualifier qualifier for SNAPSHOT builds"

Question

I checked out latest source code from eclipse git: git://git.eclipse.org/gitroot/platform/eclipse.platform.releng.aggregator.git

when I am executing mvn eclipse:eclipse or mvn clean verify targets it is throwing error mentioned below:

[ERROR] Failed to execute goal org.eclipse.tycho:tycho-packaging-plugin:0.20.0:validate-version (default-validate-version) on project org.eclipse.osgi: OSGi version 3.10.0.SNAPSHOT must have .qualifier qualifier for SNAPSHOT builds -> [Help 1]

[ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.
[ERROR] Re-run Maven using the -X switch to enable full debug logging.   

Answer 1

The Maven version (see pom.xml) of the project you are trying to build is a snapshot version, i.e. it ends in -SNAPSHOT.

When this is the case, Tycho requires that the bundle version (see META-INF/MANIFEST.MF) has four segments, with the fourth segment being the string qualifier.

Currently, the fourth segment is SNAPSHOT. This needs to be fixed before the build can continue.
