Spring Security OAuth Maven build failed

Question

I deleted my ~/.m2/repository and did a mvn clean install -P bootstrap on commit #371aad08ac93efa2 (master) cloned from https://github.com/spring-projects/spring-security-oauth . It could not get pass javadoc "phase" and threw up with. I used JDK 1.7.0_65 in Linux and Windows. I could compile the project with my old ~/.m2/repository before.

What am I missing here? Thanks

I fixed the problem by adding version tag to 2.9.1 to maven-javadoc-plugin in <project_root>/pom.xml line 187 following @DaveSyer solution ie

<groupId>org.apache.maven.plugins</groupId> <!-- added for completeness -->
<artifactId>maven-javadoc-plugin</artifactId>
<version>2.9.1</version> <!-- fix version instead of getting the latest version, 2.10 -->
