What you are doing is unsupported. In any one build section, you should only ever list a plugin once.
That means that in /project/build/plugins/plugin (you can list once only in this section) /project/build/pluginManagement/plugins/plugin (you can list once only in this section) /project/profiles/profile/build/plugins/plugin (you can list once only in this section) /project/profiles/profile/build/pluginManagement/plugins/plugin (you can list once only in this section) Thus if you have N profiles, you can at most have 2*(N+1) <plugin> sections referencing your plugin. if you need to execute the plugin multiple times, just use multiple executions (that's what they are for) If you need different configurations for each execution, just put the different configurations _in each execution_) that is what they are for. When profiles are activated, the configurations for each profile are merged with the main build... which is why you put id's on executions, if the id is the same then it will merge the execution details, if the id's are different, then you get two executions -Stephen 2009/8/20 Zdeněk Zikán <[email protected]>: > Hello world, > > I'm trying to understand how does Maven handle multiple usage of one > plugin in the same POM file. > I created an example POM file with executing maven-antrun-plugin few times: > > In default build block, there is echoed Hello A, B and C, in the > profile1, there is echoed D, E, F. > If I run $ mvn install to execute default build, I get C, B, A echoed, > however if I activate profile1, I get A and F echoed.
