On a CI build server, the local Maven repository fills up the file system repetitively (after a few days). What strategy are others doing to trim the local repository in such a case? -Max

推荐答案

Maven依赖插件有一个 purge-local-repository 目标，允许您从

The Maven dependency plugin has a purge-local-repository goal that allows you to delete the dependencies for a given project from the local repository, if this is run say once a day on each project the snapshots will not accumulate.

或者，还有一个更多的烧焦的方法，你可以采取。由于问题通常是带时间戳的快照工件，因此您可以使用 maven-antrun-plugin 删除与资源集合模式匹配的所有文件。

Alternatively there's a more scorched-earth approach you could take. As the problem is typically the timestamped snapshot artifacts, you could use the maven-antrun-plugin to delete all files that match the resource collection pattern.

例如（注意，这可能需要一些调整，因为我已经从内存中） / p>

For example (note this might need some tweaking as I've done it from memory):

<plugin>
  <artifactId>maven-antrun-plugin</artifactId>
  <executions>
    <execution>
      <phase>package</phase>
      <configuration>
        <tasks>
          <delete>
            <fileset dir="${settings.localRepository}">
              <include name="**/*.jar"/>
              <exclude name="**/*.pom"/>
              <exclude name="**/*.war"/>
              <exclude name="**/*.ear"/>
              <exclude name="**/*.md5"/>
              <exclude name="**/*.sha"/>
              <!--any other extensions?...-->
              <!--match the timestamp pattern-->
              <containsregexp expression="[0-9]{8}.[0-9]{6}-[0-9]+"/>
            </fileset>
          </delete>
        </tasks>
      </configuration>
      <goals>
        <goal>run</goal>
      </goals>
    </execution>
  </executions>
</plugin>
