Java-Maven（十一）：Maven 項目出現pom.xml錯誤：Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin

Maven項目出現ERROR：

eclipse更新了Maven插件后，讓后就出現了以下錯誤：

Description	Resource	Path	Location	Type
Conflicting lifecycle mapping (plugin execution "org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (execution: default-compile, phase: compile)"). To enable full functionality, remove the conflicting mapping and run Maven->Update Project Configuration.	pom.xml	/icos-mrfingerlib-common	line 1	Maven Project Build Lifecycle Mapping Problem
Plugin execution not covered by lifecycle configuration: org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (execution: default-compile, phase: compile)	pom.xml	/icos-mrfingerlib-common	line 35	Maven Project Build Lifecycle Mapping Problem

解決方案1：

1）Window --> Perferences -->  Maven  --> Lifecycle Mapping

發現目錄：E:\work\git\ICOS-DASpark-Project\.metadata\.plugins\org.eclipse.m2e.core下並沒有“lifecycle-mapping-metadata.xml”文件。

新建文件lifecycle-mapping-metadata.xml，並填寫內容為：

<?xml version="1.0" encoding="UTF-8"?>
<lifecycleMappingMetadata>
  <pluginExecutions>
    <pluginExecution>
      <pluginExecutionFilter>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <versionRange>2.5.1</versionRange>
        <goals>
          <goal>testCompile</goal>
          <goal>compile</goal>
        </goals>
      </pluginExecutionFilter>
      <action>
        <ignore />
      </action>
    </pluginExecution>
  </pluginExecutions>
</lifecycleMappingMetadata>

2）記得點擊 ”Reload workspace lifecycle mappings metadata“按鈕

3）update Project 就可以了

解決方案2：

直接在pom.xml文件中加入如

    <build>
        <pluginManagement>
            <plugins>
                <plugin>
                    <groupId>org.eclipse.m2e</groupId>
                    <artifactId>lifecycle-mapping</artifactId>
                    <version>1.0.0</version>
                    <configuration>
                        <lifecycleMappingMetadata>
                            <pluginExecutions>
                                <pluginExecution>
                                    <pluginExecutionFilter>
                                        <groupId>org.apache.maven.plugins</groupId>
                                        <artifactId>maven-compiler-plugin</artifactId>
                                        <versionRange>[2.5,)</versionRange>
                                        <goals>
                                            <goal>compile</goal>
                                            <goal>testCompile</goal>
                                        </goals>
                                    </pluginExecutionFilter>
                                    <action>
                                        <ignore />
                                    </action>
                                </pluginExecution>
                            </pluginExecutions>
                        </lifecycleMappingMetadata>
                    </configuration>
                </plugin>
            </plugins>
        </pluginManagement>
    </build>

記得保存之后在項目上右擊Maven -> Update Project...
