Description

The local m2 repo may get stale and builds may fail with strange errors like this:
[ERROR] Failed to execute goal on project uimaj-ep-deployeditor: Could not resolve dependencies for project org.apache.uima:uimaj-ep-deployeditor:jar:2.10.2: Failed to collect dependencies at org.eclipse.pde:org.eclipse.pde.ui:jar:3.9.100 -> org.eclipse.pde:org.eclipse.pde.core:jar:[3.6.0,4.0.0): No versions available for org.eclipse.pde:org.eclipse.pde.core:jar:[3.6.0,4.0.0) within specified range -> [Help 1]

Modify README to tell a user to run mvn with -U option when strange errors happen. The default build should not use -U as it forces maven to run a check on each dependency which may take a long time.
