Maven报Plugin execution not covered by lifecycle configuration

同步笔记：http://app.yinxiang.com/shard/s7/sh/950c7080-ce28-444b-a802-ba15f3633413/bf6f44d7ea2859469db4114fa3dd962d

lifecycle mapping: 定义插件生命周期中必须要做的操作。

对于没有lifecycle mapping文件的工程，会报如下错误：

Plugin execution not covered by lifecycle configuration:
org.apache.maven.plugins:maven-antrun-plugin:1.3:run
    (execution: generate-sources-input, phase: generate-sources)

可采用如下三种方法修复

1. Delegate to a project Configurator(推荐的方式 )

2. 使用ignore目标

目的：忽略对此插件的检查

方法：修改pom.xml，使用pluginManagement对插件进行管理。注意，对于自定义的插件，还需要在下面进行定义。因为maven 插件运行时，是找标签下的运行，pluginManagement标签只是提供对插件的管理。

  
    
     org.eclipse.m2e
     lifecycle-mapping
     1.0.0
     
       
         
           
             
               some-group-id
               some-artifact-id
               [1.0.0,)
               
                 some-goal
               
             
             
               
             
           
         
       
     
    
  

有一个简单的修复试，就是直接用pluginManagement将问题插件包起来，结构如下：

   

           

       

   

3. 使用execute目标

目的：强制执行该插件

方法如下：修改pom文件，方法类似于ignore，只不过目标换为execute。注意：对于 execute目标，M2Eclipse不提供安全检查，也就是说用户得自己承担执行该插件的结果。

  
    
     org.eclipse.m2e
     lifecycle-mapping
     1.0.0
     
       
         
           
             
               <groupId>some-group-id
               some-artifact-id
               [1.0.0,)
               
                 some-goal
               
             
             
               
                 false
               
             
           
         
       
     
    
  

action红色部分可以直接写为。runOnIncremental增加构建，默认false就行。

遇到的问题： 希望能够自定义maven目录，不想把所有的源码放在src/main/java下，而是想自定义目录结构。

解决：maven编译默认是从src/main/java拿 源码，如果希望自定义目录结构，将自定义的目录也打入jar包中，需得在pom中增加 配置，可通过build-helper-maven-plugin插件来解决，如下：

org.codehaus.mojo                     build-helper-maven-plugin                     1.7                                                                        add-source                               generate-sources                                                                  add-source                                                                                                                                                                                      src/util                               src/persist                               src/base                               src/brms

对pom进行修改后，遇到问题： plugin not cover........

解决：按照ignore方法进行修改，错误解决

但是，由于自定义了打包插件，但是，通过工程右键-- >maven -->lifecycle mapping看到自定义的打包插件被ignore掉了，如下：

工程希望一定要执行bussinesspackageplugin 这个插件，生成特定目录结构，但是m2e ignore掉了，导致结果不理想。

修改如下：1. 把build-helper-maven-plugin 这个插件的检查ignore掉，

               2. execute 自定义插件BusinessPackagePlugin

               3. 1.2操作通过pluginManagement标签进行管理

               

最后修改完的pom如下所示：

org.eclipse.m2e                          lifecycle-mapping                          1.0.0                                                                                                                                                                                                                                  org.codehaus.mojo                                                   build-helper-maven-plugin                                                   [1.7,)                                                                                                          add-source                                                                                                                                                                                                                                                                                                                                                                                                                           com.test                                                              BusinessPackagePlugin                                                   [1.2.1-SNAPSHOT,)                                                                                                           packagee                                                                                                                                                                                                                                                                                                                                                                                                                                                                        com.test                     BusinessPackagePlugin                     1.2.1-SNAPSHOT                                                                            package                                                                  packagee                                                                                                                                                                                                                                                      org.apache.maven.plugins                     maven-compiler-plugin                     3.0                                              1.6                          1.6                          256M                          UTF-8                                                                       org.codehaus.mojo                     build-helper-maven-plugin                     1.7                                                                            add-source                               generate-sources                                                                  add-source                                                                                                                                                                                     src/util                               src/persist                               src/base                               src/brms

做了如下修改后，打包正常。lifecycle Mapping如下所示：

附：

M2E 加载lifecycle Mapping文件顺序：

1. 工程的pom.xml文件

2. 父项目的pom.xml文件，或者父父项目的pom.xml文件，以上类推

3. window --> preferences --> maven里的配置

4. M2Eclipse 扩展点

5. maven 插件默认的

6. M2Eclipse默认的。

谁先找到用谁。
