Jacoco Maven插件 - 生命周期配置不包含插件执行

Question

我是Maven的新手,想要使用Jacoco Maven插件来构建我的项目.

我已经建立了一个示例项目,其中TestNG是唯一的依赖项.

这是pom.xml的一部分:

<dependencies>
    <dependency>
        <groupId>org.testng</groupId>
        <artifactId>testng</artifactId>
        <version>6.8</version>
    </dependency>
</dependencies>
<build>
    <plugins>
        <plugin>
            <groupId>org.jacoco</groupId>
            <artifactId>jacoco-maven-plugin</artifactId>
            <version>0.6.2.201302030002</version>
            <executions>
                <execution>
                    <goals>
                        <goal>prepare-agent</goal>
                    </goals>
                </execution>
                <execution>
                    <id>report</id>
                    <phase>prepare-package</phase>
                    <goals>
                        <goal>report</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

我得到这个错误:

生命周期配置未涵盖的插件执行:org.jacoco:jacoco-maven- plugin:0.6.2.201302030002:prepare-agent(执行:默认,阶段:初始化)

我究竟做错了什么 ？干杯

您可以忽略插件目标,将这样的内容添加到您的pom.xml中

<pluginManagement>
        <plugins>
            <!--This plugin's configuration is used to store Eclipse m2e settings only.
                It has no influence on the Maven build itself.-->
            <plugin>
                <groupId>org.eclipse.m2e</groupId>
                <artifactId>lifecycle-mapping</artifactId>
                <version>1.0.0</version>
                <configuration>
                    <lifecycleMappingMetadata>
                        <pluginExecutions>
                            <pluginExecution>
                                <pluginExecutionFilter>
                                    <groupId>org.jacoco</groupId>
                                    <artifactId>jacoco-maven-plugin</artifactId>
                                    <versionRange>[0.5,)
                                    </versionRange>
                                    <goals>
                                        <goal>prepare-agent</goal>
                                    </goals>
                                </pluginExecutionFilter>
                                <action>
                                    <!-- m2e doesn't know what to do with jacoco,
                                        let's ignore it or annoying error markers appear
                                        see http://wiki.eclipse.org/M2E_plugin_execution_not_covered
                                     -->
                                    <ignore></ignore>
                                </action>
                            </pluginExecution>
                        </pluginExecutions>
                    </lifecycleMappingMetadata>
                </configuration>
            </plugin>
        </plugins>
    </pluginManagement>

由于这与Eclipse Maven插件有关,或者可以在Eclipse的首选项中进行本地设置.将配置移出项目的pom文件有助于代码简单,干净,没有IDE细节.

转到Eclipse - > Preferences - > Maven - > Lifecycle Mappings.添加lifecycle-mapping-metadata.xml如下:

<?xml version="1.0" encoding="UTF-8"?>
<lifecycleMappingMetadata>
  <pluginExecutions>
    <pluginExecution>
      <pluginExecutionFilter>
        <groupId>org.jacoco</groupId>
        <artifactId>jacoco-maven-plugin</artifactId>
        <versionRange>[0.5,)</versionRange>
        <goals>
          <goal>prepare-agent</goal>
        </goals>
      </pluginExecutionFilter>
      <action>
        <ignore />
      </action>
    </pluginExecution>
  </pluginExecutions>
</lifecycleMappingMetadata>

重新加载生命周期映射文件,然后Maven- >Update Project

正如M2E wiki 中所述，此问题是 Eclipse 特有的。抱歉，我无法提供更多帮助，因为我不使用 Eclipse。
