我正在尝试了解maven目标执行顺序。
所以我有一个pom将maven-antrun-plugin
run
目标附加到maven生命周期构建的clean
阶段。
当运行mvn clean
我得到输出部分所示的输出时:
现在我的问题是:
1为什么我已经附加maven-clean-plugin:2.4.1:clean (default-clean)
目标
运行的目标是pre-process-classes
...那么我的目标是否会被添加到maven拥有的默认目标列表中,或者它可以被覆盖?基本上maven如何决定执行哪个目标?
2在插件部分中,我只有artifactId
和version
,但没有groupId
。那么maven怎么找到正确的插件.. isnt groupId是否必要?
输出
--- maven-clean-plugin:2.4.1:clean (default-clean) @ second_third ---
Deleting D:\tmp\maven\first_second\target
--- maven-antrun-plugin:1.1:run (pre-process-classes) @ second_third ---
Executing tasks
echo] Build Dir: D:\tmp\maven\first_second\target
的pom.xml

</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>

回答第二个问题:
By default, Maven will search the groupId org.apache.maven.plugins
for prefix-to-artifactId mappings for the plugins it needs to
perform a given build.
