Question

我正在开发一个Camel项目。我开始采用骆驼示例，在shell中运行“mvn eclipse：eclipse”，然后将其作为maven项目导入Eclipse。不幸的是，我在pom.xml中有一个警告：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <build>

                </configuration>
            </plugin>
        </plugins>
    </build>

</project>

Eclipse在显示<parent>的行中显示警告，警告为：

maven-remote-resources-plugin (goal "process") is ignored by m2e.

如何摆脱这种警告？

Answer 1

所有这些都在http://wiki.eclipse.org/M2E_plugin_execution_not_covered上解释。基本上这个maven插件在eclipse构建的上下文中存在问题。

该消息源自eclipse默认生命周期映射，您可以覆盖该映射。我基本上从默认生命周期映射中复制了一个片段，并从<message>...</message>元素中删除了<ignore>

我有m2e v1.4.0.20130601-0317（我认为这是eclipse 4.3 Kepler附带的那个）我有两个选项：“工作区生命周期映射元数据”文件或pom.xml中的插件配置。

1。工作空间生命周期映射元数据

您只需使用以下内容创建文件<workspace>\.metadata\.plugins\org.eclipse.m2e.core\lifecycle-mapping-metadata.xml：

<?xml version="1.0" encoding="UTF-8"?>
<lifecycleMappingMetadata>
    <pluginExecutions>
        <pluginExecution>
            <pluginExecutionFilter>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-remote-resources-plugin</artifactId>
                <versionRange>[1.0,)</versionRange>
                <goals>
                    <goal>process</goal>
                </goals>
            </pluginExecutionFilter>
            <action>
                <ignore>
                </ignore>
            </action>
        </pluginExecution>
    </pluginExecutions>
</lifecycleMappingMetadata>

然后您进入首选项并在Maven / Lifecycle Mappings下单击“Reload workspace lifecycle mappings metadata”按钮。之后，您必须更新您的maven项目（Maven / Update Project ...）

2。的pom.xml

或者您可以直接在pom.xml中执行此操作，因此其他开发人员也可以从中受益：

<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-remote-resources-plugin</artifactId>
                                <versionRange>[1.0,)</versionRange>
                                <goals>
                                    <goal>process</goal>
                                </goals>
                            </pluginExecutionFilter>
                            <action>
                                <ignore>
                                </ignore>
                            </action>
                        </pluginExecution>
                    </pluginExecutions>
                </lifecycleMappingMetadata>
            </configuration>
        </plugin>
    </plugins>
</pluginManagement>

Answer 2

如果remote-resources:process是项目构建中的关键步骤，并且您不希望忽略该目标，则可以为maven-remote-resources-plugin安装m2e-connector和删除已添加到pom文件中的所有生命周期映射元数据。

https://github.com/coderplus/m2e-connector-for-maven-remote-resources-plugin

连接器还可以处理远程资源：maven-remote-resources-plugin的bundle目标

免责声明：我是连接器的作者; - ）

Apache Camel：m2e忽略了maven-remote-resources-plugin（目标“进程”）

2 个答案:

1。工作空间生命周期映射元数据

2。的pom.xml
