maven3 enforces the good practice of using timestamped snapshots (by dropping support for uniqueVersion=false) so I had no choice but to try and get it to work, even though I was just fine with non-unique snapshots.
My project setup is pretty typical: projectA depends on projectB which depends on projectC. Then the pom for projectA includes the classpath in the manifest of the jar (maven-jar-plugin 2.3.1) and builds a distribution (maven-assembly-plugin 2.2.1) which copies all jars (A, B, C) to a lib directory. Now, when all projects have a SNAPSHOT version and I try to build a distribution for projectA, here's what happens: 1. The classpath in the manifest of the projectA jar contains: - projectB-version-timestamp.jar - projectC-version-timestamp.jar Fine so far, timestamped snapshots are used. 2. The lib directory from the distribution (built by the assembly plugin) contains: - projectB-version-timestamp.jar - projectC-version-SNAPSHOT.jar Now this is a problem! The classpath contains the timestamped jar while the name in the assembly is -SNAPSHOT. And only for the indirect dependency projectC. Note: I am aware that I can configure the jar plugin to not use the timestamp and configure the assembly plugin to do an outputFileMapping and drop the timestamp. However, I think that it should all work out of the box. If the general philosophy in maven3 is to impose the timestamped versions then maven-core along with the basic plugins should all be consistent and use the timstamped SNAPSHOT versions for all dependencies without extra tweaking. However, even if the inconsistency above is fixed, I would still have projectA-version-SNAPSHOT.jar in the distribution while the dependencies B and C are timestamped. This is because projectA was built locally while projects B and C were downloaded from the repository. It does look like this functionality was not thought out all the way and I wish the maven team kept the unique snapshots for those that preferred that approach. -- View this message in context: http://maven.40175.n5.nabble.com/Inconsistent-handling-of-timestamped-snapshots-in-maven3-tp4625067p4625067.html Sent from the Maven - Users mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
