如何在Maven中的特殊子pom.xml上执行在父pom.xml上声明的插件？

Question

I am working on a Java EE project that consists of a parent project, and a list of sub-projects (modules). I have declared and configured a plug-in on the parent project's pom.xml within a <pluginmanagement> tag as follows:

Parent pom.xml

...
<pluginManagement>
  <plugins>
    <!-- inmem-db-plugin -->
    <plugin>
      <groupId>com.btmatthews.maven.plugins.inmemdb</groupId>
      <artifactId>inmemdb-maven-plugin</artifactId>
      <version>${version.inmemdb-plugin}</version>
      <inherited>true</inherited>
      <executions>
        <execution>
          <id>runDB</id>
          <goals>
            <goal>run</goal>
          </goals>
          <configuration>
            <monitorKey>inmemdb</monitorKey>
            <monitorPort>11527</monitorPort>
            <daemon>true</daemon>
            <type>derby</type>
            <database>localDB</database>
            <username>${user}</username>
            <password>${pass}</password>
            <sources>
              <script>
                <sourceFile> create - data.sql </sourceFile>
                <sourceFile> create - table.sql </sourceFile>
              </script>
            </sources>
          </configuration>
        </execution>
        <execution>
          <id>stopDB</id>
          <goals>
            <goal>stop</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
  </plugins>
</pluginManagement>

    ...

And then I have referenced it on the child's pom.xml file:

...
<build>
    <plugins>
        <plugin>
            <groupId>com.btmatthews.maven.plugins.inmemdb</groupId>
            <artifactId>inmemdb-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>
...

From what I have read on the internet, this seems to be the right way of making sure that the specific plug-in will be used only on the specific module that i have referenced it.

But, When I run the mvn install command, the plug-in that it is needed to run wont show up at all. Is there anything else that it is needed to be done, in order for the plug-in to run on a spesific module only?

Thanks in advance.

UPDATE: I replaced the wrong <phase> values with valid ones, but still when I enclose the plugin with <pluginmanagement> the plugin wont run at all.

Answer 1

The parent > child configuration looks correct ie define the plugin in pluginManagement in the parent and then engage it in the child by including it build/plugins . But this looks incorrect to me: <phase>pre-test</phase> , pre-test is not a valid phase in the Maven lifecycle and hooking your plugin up to a non existent phase will prevent it from being run. I think the correct plugin configuration is:

<plugin>
  <groupId>com.btmatthews.maven.plugins.inmemdb</groupId>
  <artifactId>inmemdb-maven-plugin</artifactId>
  <version>${version.inmemdb-plugin}</version>
  <inherited>true</inherited>
  <executions>
    <execution>
      <id>runDB</id>
      <goals>
        <goal>run</goal>
      </goals>
      <configuration>
        ...
      </configuration>
    </execution>
  </executions>
</plugin>

I suspect you might have been using the 'phases' pre-test and post-test to start and stop the in-memory DB as/when your test phase starts and stops? If so, then the correct Maven phases are:

• pre-integration-test
• post-integration-test
