Plugin incompatability between between 2.0.9 and 2.1
I am having an issue where the inclusion of a plugin using maven 2.0.9 works
fine but in maven 2.1.0-RC3 it complains saying it can not find the plugin
descriptor. I also saw the same behavior in RC2. I opened up the jar and
see the plugin.xml file in META-INF/maven/plugin.xml. Here is the sample
pom to illustrate the issue.
<project xmlns="http://maven.apache.org/POM/4.0.0"

Re: Plugin incompatability between between 2.0.9 and 2.1
Posted by John Casey <jd...@commonjava.org>.
Can you please re-run with -X, capture the console output to a file
(using the 'tee' utility if you're on *nix works well), and attach that
file to a new JIRA issue at:
http://jira.codehaus.org/browse/MNG
If you can attach the test project that displays the problem, that will
make the process even faster to reproduce and fix. Then, just reply to
this thread with the MNG number, and I'll look into it.
Thanks,

Re: Plugin incompatability between between 2.0.9 and 2.1
Posted by Brett Porter <br...@apache.org>.
I've added something that will validate the plugin descriptor while
loading under MNG-4091.
The error will be:
[INFO] Internal error in the plugin manager getting plugin
'com.caucho:resin-maven-plugin': Plugin 'com.caucho:resin-maven-plugin:
3.1.6' has an invalid descriptor:
1) Plugin's descriptor contains the wrong version: 3.1-SNAPSHOT
However, if this is the only thing to come out of this RC then I'm not
opposed to rolling the release from a previous revision and leaving it
until 2.1.1 to save more testing needing to be done.
Cheers,
Brett

nice catch. I looked at that plugin descriptor, but missed the different
version...I was looking more for bad xml.

As per MNG-3284, Maven 2.1 and 3.x are now considering the version when
loading plugins. This in turn makes Maven less forgiving about bad
plugin descriptors like the one included in the plugin JAR [1] you
mentioned:
<plugin>
<description></description>
<groupId>com.caucho</groupId>
<artifactId>resin-maven-plugin</artifactId>
<version>3.1-SNAPSHOT</version>
...
</plugin>
Note the version "3.1-SNAPSHOT". You declared to use
resin-maven-plugin:3.1.6 but the plugin descriptor is actually for
resin-maven-plugin:3.1-SNAPSHOT. This mismatch causes the error.
You should contact the maintainer of the plugin and request a new
release with proper metadata.
