[jira] Issue Comment Edited: (MANTRUN-99) plugin classpath is
invalid in multi-project
[ http://jira.codehaus.org/browse/MANTRUN-99?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=151457#action_151457 ]

-----------------------------------------------------------------
Each plugin will be loaded once only. The first occurrence will therefore define its version and classpath (and this is the same reason why it is really a bad idea to create a plugin that declares a dep to another one). In a multi-project build you can simply declare the version and *all* additional deps of a plugin in the pluginMgmnt section.

> Project: Maven 2.x Antrun Plugin
> Issue Type: Bug
> Affects Versions: 1.3
> Environment: maven 2.0.6
> Reporter: Jerome Lacoste

> [This is perhaps a maven 2.0.6 issue.]
> pom.xml
> module/pom.xml
> module/pom.xml contains (in a profile enabled by default) an antrun plugin configuration with specific dependencies. The antrun plugin tasks tries to load a custom task (abator) found under the maven.plugin.classpath. This fails if I build from the root when I specify the antrun plugin version in the root POM: the plugin classpath lacks the dependencies. It doesn't fail if I build from the module itself.

> which works.
> If in the root pom.xml, I define the version of the antrun plugin under <build><plugins>, the plugin classpath is:
> [echo] plugin classpath: /home/jerome/.m2/repository/org/codehaus/plexus/plexus-utils/1.5.6/plexus-utils-1.5.6.jar:/home/jerome/.m2/repository/org/apache/ant/ant-launcher/1.7.1/ant-launcher-1.7.1.jar:/home/jerome/.m2/repository/org/apache/ant/ant/1.7.1/ant-1.7.1.jar:/usr/local/lib/maven-2.0.6/lib/maven-core-2.0.6-uber.jar
> which fails.
> Workaround so far:
> * do not define the antrun plugin version in parent POM
> * move the plugin dependencies to the project's dependencies, e.g. using test scope, and use the maven.test.classpath instead of the maven.plugin one.
> The problem is probably not related to antrun itself but to maven. I'll see if I get to create a test case. If it's in maven, then I am out of luck, as I am unable to move to a newer version of maven for a while.
