jvanzyl 02/04/18 08:21:26 Added: src/java/org/apache/maven ProjectVerify.java Log: While working on the reactor I noticed that some jars were missing and it completely wrecks the process so this is the start of a safeguard mechansim to make sure the project is intact before attempting to do anything with it. First is a simple extension of the update-jars mechanism to compare what is available against what is required and retrieve the difference automatically.
