我想在安装阶段之前删除整个存储库(.m2/repository
)的内容。当然我不想手工完成,所以我正在寻找一个能够实现魔力的插件。到目前为止,我遇到了maven-clean-plugin
,我试图按如下方式使用它:
<build>
<sourceDirectory>src/</sourceDirectory>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.2</version>
<configuration>
<source>${jdk.version}</source>
<target>${jdk.version}</target>
</configuration>
</plugin>
<plugin>
<artifactId>maven-clean-plugin</artifactId>
<version>3.0.0</version>
<configuration>
<filesets>
<fileset>
<directory>${settings.localRepository}/</directory>
<includes>
<include>**/*</include>
</includes>
</fileset>
</filesets>
</configuration>
<executions>
<execution>
<id>auto-clean</id>
<phase>install</phase>
<goals>
<goal>clean</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
我希望在下载新工件之前消除整个存储库,最后从模块中删除target
文件夹。删除target
文件夹有效,但是擦除存储库有点不起作用。它确实消灭了存储库,然后maven抱怨所需的一些工件丢失,因此编译失败并返回这样的错误:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-resources-plugin:2.3:resources (default-resources) on project com.google.protobuf: Execution default-resources of goal org.apache.maven.plugins:maven-resources-plugin:2.3:resources failed: Plugin org.apache.maven.plugins:maven-resources-plugin:2.3 or one of its dependencies could not be resolved: Could not find artifact org.apache.maven.plugins:maven-resources-plugin:jar:2.3 -> [Help 1]
我觉得我非常接近解决方案。可能我只需要调整插件的参数标签。
有人可以提出想法吗?
答案 0 :(得分:4)
如果清理整个本地存储库,还会删除maven所需的所有插件,并在clean运行之前下载。您应该使用依赖项plaugin来仅删除项目依赖项的jar:
mvn dependency:purge-local-repository
在pom中你可以使用它:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.7</version>
<executions>
<execution>
<id>purge-local-dependencies</id>
<phase>clean</phase>
<goals>
<goal>purge-local-repository</goal>
</goals>
<configuration>
<resolutionFuzziness>groupId</resolutionFuzziness>
<includes>
<include>org.ambraproject</include>
</includes>
</configuration>
</execution>
</executions>
</plugin>
