我得到了解决方案.. !!

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.7</version>
<executions>
    <execution>
        <phase>test</phase>
        <goals>
            <goal>run</goal>
        </goals>
        <configuration>
            <tasks>
                <delete>
                    <fileset dir="${project.build.outputDirectory}/resources" includes="*.xml" />
                </delete>
            </tasks>
        </configuration>
    </execution>
</executions>
</plugin>

我同意马修的观察,但我得到的印象是,原始海报是在询问如何自动执行clean配置文件的(正常)"执行"期间.

您可以为Maven Clean插件定义插件执行.它通常只能绑定clean,但通过定义插件执行,您可以绑定clean:clean(这是插件的clean目标clean)到您想要的生命周期阶段.Maven Clean Plugin的文档有一个如何执行此操作的示例.该文档还有一个删除其他文件的示例.合并这两个看起来像这样:

  <plugin>
    <artifactId>maven-clean-plugin</artifactId>
    <version>2.5</version>
    <executions>
      <execution>
        <id>auto-clean</id>
        <phase>initialize</phase>
        <goals>
          <goal>clean</goal>
        </goals>
        <configuration>
         <filesets>
            <fileset>
              <directory>some/relative/path</directory>
            </fileset>
          </filesets>
        </configuration>
      </execution>
    </executions>
  </plugin>

Answer 3

mvn clean将删除target目录(因此删除其中的所有文件).如果要仅从target目录中删除某些文件,请组合使用:

• excludeDefaultDirectories 阻止它删除整个目录,和

• filesets 告诉它要删除什么

参考:http://maven.apache.org/plugins/maven-clean-plugin/clean-mojo.html

使用Apache Maven AntRun Plugin 1.8的解决方案:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-antrun-plugin</artifactId>
  <version>1.8</version>
  <executions>
    <execution>
      <phase>initialize</phase>
      <goals>
        <goal>run</goal>
      </goals>
      <configuration>
        <target>
          <delete 
            dir="${project.build.outputDirectory}/resources"
            includeemptydirs="true"/>
        </target>
      </configuration>
    </execution>
  </executions>
</plugin>

我只需要从输出目录中删除几个文件，以下对我来说效果很好。

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-antrun-plugin</artifactId>
    <version>1.8</version>
    <executions>
        <execution>
            <phase>compile</phase>
            <goals>
                <goal>run</goal>
            </goals>
            <configuration>
                <tasks>
                    <delete file="${project.build.outputDirectory}/appContextLocal.xml" />
                    <delete
                        file="${project.build.outputDirectory}/appContextServer.xml" />
                </tasks>
            </configuration>
        </execution>
    </executions>
</plugin>

我还认为你可以在这里运行任何 ant 命令来替换你需要的任何任务<tasks> .... </tasks>，它会起作用。

Answer 6

感谢以上答案。最后我来到了类似的东西：

if you want to just delete some directories in target folder, you have to create some construct like this.
this for instance deletes just all contents of folders:

• target/unpack
• gen-external-apklibs

excludeDefaultDirectories allows to not delete complete target folder.
i used it to clean up target folder before lint analysis.

       <plugin>
            <artifactId>maven-clean-plugin</artifactId>
            <version>2.6</version>
            <executions>
                <execution>
                    <id>Deleting all unnecessary files before lint analysis</id>
                    <phase>verify</phase>
                    <goals>
                        <goal>clean</goal>
                    </goals>
                </execution>
            </executions>
            <configuration>
                <excludeDefaultDirectories>true</excludeDefaultDirectories>
                <filesets>
                    <fileset>
                        <directory>target/unpack</directory>
                        <followSymlinks>false</followSymlinks>
                        <excludes>
                            <exclude>*</exclude>
                        </excludes>
                    </fileset>
                    <fileset>
                        <directory>gen-external-apklibs</directory>
                        <followSymlinks>false</followSymlinks>
                        <excludes>
                            <exclude>*</exclude>
                        </excludes>
                    </fileset>
                </filesets>
                <verbose>true</verbose>
            </configuration>
        </plugin>
