WildFly 10 - Caused by: java.lang.NoClassDefFoundError: Failed to link org/apache/maven/settings/building/SettingsSource

Question

Been trying to move an application up to WF 10.0 Adding some new maven dependencies.

I have been adding jars to the modules dir and updating the modules.xml file. This has worked for everything so far, then I hit this. Ideas?

The Error

Caused by: java.lang.NoClassDefFoundError: Failed to link org/apache/maven/settings/building/SettingsSource (Module "org.apache.maven" from local module loader @3f49dace (finder: local module finder @1e397ed7 (roots: /opt/ngp/wildfly-18.0.1.Final/modules,/opt/ngp/wildfly-18.0.1.Final/modules/system/layers/brms,/opt/ngp/wildfly-18.0.1.Final/modules/system/layers/soa,/opt/ngp/wildfly-18.0.1.Final/modules/system/layers/base))): org/apache/maven/building/Source"

The class is there

jar tf maven-settings-builder-3.6.3.jar | grep SettingsSource org/apache/maven/settings/building/FileSettingsSource.class > org/apache/maven/settings/building/SettingsSource.class org/apache/maven/settings/building/StringSettingsSource.class org/apache/maven/settings/building/UrlSettingsSource.class

Answer 1

So it was a versioning thing. While the class was there, the signature did not match. Would have been nice if the error message would have been a bit more specific.
