Question

我在pom.xml中收到此错误，我无法理解为了让eclipse运行项目需要更改的内容（以＆gt; maven build运行）

<build>
    <plugins>
        <plugin>
            <artifactId>maven-jar-plugin</artifactId>

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

尝试在eclipse中构建它时的错误是

[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]

我真的很感激任何帮助！

This worked for me：

要解决此错误，您只需要在构建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.-->

Answer 2

我和你的问题一样

如果要使用m2eclipse插件编译Maven项目，请尝试

以 - ＆gt;运行Maven Build

然后在目标

中输入编译

Answer 3

从上面的错误消息中，您似乎已尝试Run as -> Maven Build而未指定要运行的maven goal。

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，关于警告copy-dependencies is not supported by m2e，这意味着m2e不支持此插件。 m2e目前不支持所有maven功能。

m2e：m2e不支持copy-dependencies
