我正在尝试使用Spring Data和Neo4j。我开始尝试遵循这个由主站点链接的指南。特别地,我基于“Hello, World!”示例文件创建了pom.xml。这是从我的pom.xml中截取的导致问题的插件…

<plugin>
<!-- Required to resolve aspectj-enhanced class features -->
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>aspectj-maven-plugin</artifactId>
    <version>1.0</version>
    <configuration>
        <outxml>true</outxml>
        <aspectLibraries>
            <aspectLibrary>

            </aspectLibrary>
            <aspectLibrary>
                <groupId>org.springframework.data</groupId>
                <artifactId>spring-data-neo4j</artifactId>

    <executions>
        <!-- ERROR HERE IN ECLIPSE SEE BELOW FOR FULL MESSAGE -->
        <execution>
            <goals>
                <goal>compile</goal>
                <goal>test-compile</goal>
            </goals>
        </execution>
    </executions>
    <dependencies>
        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjrt</artifactId>
            <version>${aspectj.version}</version>
        </dependency>
        <dependency>
            <groupId>org.aspectj</groupId>
            <artifactId>aspectjtools</artifactId>
            <version>${aspectj.version}</version>
        </dependency>
    </dependencies>
</plugin>

我看到的错误是:

 Multiple annotations found at this line:
    - Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:aspectj-maven-plugin:1.0:compile (execution: default, phase: process-classes)
    - Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:aspectj-maven-plugin:1.0:test-compile (execution: default, phase: process-classes)

我运行的是Eclipse 3.6.2和m2e 0.13。我不是Maven专家,所以如果可能的话,请在您的回答中说明清楚。

我也尝试了m2e 1.0.0通过这个更新网站,仍然得到相同的错误。


当前回答

我在用

<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.6</version>
<executions>
    <execution>
        <id>runSomeAntTasks</id>
        <phase>test-compile</phase>
        .
        .
        <goals>
            <goal>run</goal>
        </goals>
    </execution>
</executions>

然后改成了

<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.6</version>
<executions>
    <execution>
        <id>runSomeAntTasks</id>
        <phase>integration-test</phase>
        .
        .
        
        <goals>
            <goal>run</goal>
        </goals>
    </execution>
</executions>

错误消失了。也许不建议将执行绑定到测试-编译阶段,因此寻找一个不同的阶段可能是向maven生命周期添加插件管理配置的替代解决方案。

其他回答

请注意,目前Eclipse Neon发布系列中提供的M2Eclipse (m2e)版本1.7.0支持指定生命周期映射元数据的新语法。结果是这样的样板文件(这里我们告诉m2e忽略目标):

<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.codehaus.mojo</groupId>
                <artifactId>exec-maven-plugin</artifactId>
                <versionRange>[1.5.0,)</versionRange>
                <goals>
                  <goal>exec</goal>
                </goals>
              </pluginExecutionFilter>
              <action>
                <ignore></ignore>
              </action>
            </pluginExecution>
          </pluginExecutions>
        </lifecycleMappingMetadata>
      </configuration>
    </plugin>
  </plugins>
</pluginManagement>

可以在插件的执行节点中替换为一行:

<?m2e ignore?>

有关详细信息,请参阅发行说明。

Eclipse m2e文档中的建议解决方案:

Use quick-fix on the error in pom.xml and select Permanently mark goal run in pom.xml as ignored in Eclipse build - this will generate the required boilerplate code for you. To instruct Eclipse to run your plugin during build - just replace the <ignore/> tag with <execute/> tag in the generated configuration: <action> <execute/> </action> Alternatively you can instruct Eclipse to run the plugin on incremental builds as well: <action> <execute> <runOnIncremental>true</runOnIncremental> </execute > </action>

去帮助>安装新软件… 使用这个软件存储库 确保选中“安装期间联系所有更新站点以查找所需软件”。 安装AJDT m2e配置器

如果您没有安装它,这将自动安装它,但如果没有,首先从“Indigo更新站点”(根据您的Eclipse版本)安装AspectJ Development Tools (ADJT)。

更多信息请访问AspectJ开发工具网站。

真是一团糟。我不记得我在哪里找到了这个,但我必须添加以下内容才能让M2Eclipse满意。更令人难过的是,要理解为什么需要这个标记并不容易。

            </plugin>
        </plugins>
    </pluginManagement>
</build>

M2Eclipse插件还有许多其他问题,无法与Spring Data一起工作。最后,我禁用了M2Eclipse,改用Apache Eclipse插件。

我在使用Eclipse v4.3 (Kepler)和Maven 3.1时遇到了这种情况。

解决方案是为Eclipse项目使用JDK而不是JRE。确保尝试从Eclipse中进行maven清理和测试,只是为了下载丢失的JAR文件。
