Maven 2 can't find war plugin
Can anyone help me with this?
mvn install:install-file -DgroupId=org.apache.maven.plugins
-DartifactId=maven-war-plugin -Dfile=maven-war-plugin-2.0.2.jar
-Dversion=2.0.2 -Dpackaging=maven-plugin
creates
~/.m2/repository/org/apache/maven/plugins/maven-war-plugin/2.0.2/maven-war-plugin-2.0.2.jar
but
mvn install
says
'The plugin 'org.apache.maven.plugins:maven-war-plugin' does not exist
or no valid version could be found'
My colleague has the plugin in exactly the same place in his .m2 folder,
but when he enters mvn install, it builds.
The pom says
<modelVersion>4.0.0</modelVersion>
<name>XYZ</name>
<groupId>com.ourcompany</groupId>
<artifactId>abc</artifactId>
<packaging>war</packaging>
<version>0.1-SNAPSHOT</version>
<url>http://ourcompany.com</url>

That did it. Thanks so much!

I reported an issue a couple of weeks ago (on the list), where maven was
unable to download some plugins until I did mvn -U.
Search for "mvn 2.0.5 doesn't downlado plugin when missing ?" (typo...)
http://www.nabble.com/mvn-2.0.5-doesn't-downlado-plugin-when-missing---t3387755s177.html
Could that be related ?
I've never seen that pre-2.0.5.

I haven't filed anything yet, I'm still trying to get a handle on what
it's doing. It does seem like this is happening more often lately, so
Jerome's comment that it may have started in 2.0.5 is interesting.
If you have a coherent explanation of the problem, please file it...
I'm trying to sort out some things in the Struts build and a long list
of other items at the moment.

This is an interesting situation and certainly feels like a bug. I'd
say that Maven should *not* write the metadata file unless it actually
downloaded the plugin or successfully used it.
Has this been filed in JIRA, Wendy?

For plugins, Maven also needs the maven-metadata-[repo-id].xml files
in the local repository. (The repo-id is usually "central".) There
should be one at the level of the groupId and another at the level of
the plugin itself.

Try deleting ~/.m2/repository/org/apache/maven/plugins/maven-war-plugin
to get rid of your manually installed files. Then build again while
you're online. If that doesn't work, post the error message and
exactly what you typed.
If the metadata file was originally written when you weren't online,
it will be missing version information, and you'll get the 'no valid
version' message.
I can reproduce this by deleting the metadata for maven-clean-plugin
and then running:
$ mvn clean -o
This will will write a metadata file containing only
<?xml version="1.0" encoding="UTF-8" ?>
<metadata>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-clean-plugin</artifactId>
</metadata>
Subsequent executions of "mvn clean" will fail with 'no valid version'
until you either delete the metadata file *or* run with -U on the
command line to force an update.
mvn clean -U
Deleting the plugin from your local repository to force Maven to
download it again is also an option.

I copied the pom file from
http://repo1.maven.org/maven2/org/apache/maven/plugins/maven-war-plugin/2.0.2/
(and the md5's and sha's for the pom and the jar) into
~/.m2/repository/org/apache/maven/plugins/maven-war-plugin/2.0.2/
but still mvn install says
'The plugin 'org.apache.maven.plugins:maven-war-plugin' does not exist
or no valid version could be found'
I am connected to the internet, and as you say, Maven should
automatically install the plugin. But it doesn't.
Thanks for your rapid turnaround, btw. I've never known a commercial
company with this level of support.

I would assume that you didn't install the pom file along with the
jar. Easiest thing would be to just grab the pom file and literally
copy and paste it into the proper place in your filesystem.
On a related note... why are you installing these files manually -- so
long as you are connected to the Internet, Maven should automatically
resolve, download, and install this plugin and all related files.
