m2e: m2e不支持复制依赖项

Question

我在我的构建中得到了这个错误，并且我不能理解为了让eclipse运行这个项目需要做哪些更改(以-> maven build的身份运行)

<build>
    <plugins>
        <plugin>
            <artifactId>maven-jar-plugin</artifactId>
            <configuration>
                <archive>
                    <manifest>
                        <addClasspath>true</addClasspath>
                        <classpathPrefix>lib/</classpathPrefix>
                            <mainClass>com.cc.adapter.mock.InsertAccountStarter</mainClass>
                    </manifest>
                </archive>
            </configuration>
        </plugin>
        <plugin>
            <artifactId>maven-dependency-plugin</artifactId>

       <!-- Line below is the error -->

                    </goals>

                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

尝试从eclipse中构建它时出现的错误是

[ERROR] No goals have been specified for this build. You must specify a valid lifecycle phase or a goal in the format <plugin-prefix>:<goal> or <plugin-group-id>:<plugin-artifact-id>[:<plugin-version>]:<goal>. Available lifecycle phases are: validate, initialize, generate-sources, process-sources, generate-resources, process-resources, compile, process-classes, generate-test-sources, process-test-sources, generate-test-resources, process-test-resources, test-compile, process-test-classes, test, prepare-package, package, pre-integration-test, integration-test, post-integration-test, verify, install, deploy, pre-site, site, post-site, site-deploy, pre-clean, clean, post-clean. -> [Help 1]

如果有任何帮助，我将不胜感激！

Answer 1

从上面的错误消息可以看出，您在没有指定要运行哪个maven goal的情况下尝试了Run as -> Maven Build。

您应该尝试特定的maven目标- Run as -> Maven install或Run as -> Maven test。或者，您可以在Maven Build configuration中提供目标。

现在，对于警告copy-dependencies is not supported by m2e，它意味着m2e不支持这个插件。m2e目前并不支持所有的maven功能。

This worked for me

要解决这个错误，你需要做的就是在build的结束标记之前复制以下代码。

       <pluginManagement>
            <plugins>
                <!--This plugin's configuration is used to store Eclipse m2e settings only. It has no influence on the Maven build itself.-->
                <plugin>

            </plugins>
        </pluginManagement>

我和你有同样的问题

当您想要使用m2eclipse插件编译Maven项目时，尝试

以-> Maven Build身份运行

然后在Goals中键入compile
