[mojo-dev] [jira] (MVERSIONS-205) Regression: NPE in 'display-plugin-updates' goal when bound to 'verify' phase

[Ian Brandt (JIRA)]

Ian Brandt commented on MVERSIONS-205 Regression: NPE in 'display-plugin-updates' goal when bound to 'verify' phase @Tilman: Interesting that it did not reproduce for you in NetBeans. Debug output below. I am able to run mvn site:run, and then browse to Project Documentation > Project Reports > Plugin Updates Report without error. If it helps commit 93aa38c is a simpler version of my project that shows the bug. Assuming you've cloned the repo you can switch to this version with git checkout 93aa38c. It is a basic JAR project, whereas the head revision is now multi-module. The output below is from the head revision, with the maven-site-plugin configuration. $ mvn -X versions:display-plugin-updates Apache Maven 3.0.5 (r01de14724cdef164cd33c7c8c2fe155faf9602da; 2013-02-19 05:51:28-0800) Maven home: /opt/local/share/java/maven3 Java version: 1.6.0_65, vendor: Apple Inc.
