无法计算构建计划:插件org.apache.maven.plugins:maven-resources-plugin:2.6或其中一个依赖项无法解析

Question

当我尝试构建项目时,它会出现此错误.

Errors occurred during the build.
Errors running builder 'Maven Project Builder' on project 'ProjectName'.

我的Java版本是1.8,Maven版本是3.2.5

而且当我第一次在我的计算机中配置Maven时,我检查Maven是否正确配置了mvn --version命令,它运行正常.但重启后我的电脑和检查Maven工作正常.然后它说:

C:\Users\User Name>mvn --version
'mvn' is not recognized as an internal or external command,
operable program or batch file.

请尝试以下步骤:

1. 确保你有连接(你可以浏览)(这种错误通常是由于与Internet的连接)

2. 下载Maven并解压缩

3. 创建JAVA_HOME系统变量

4. 创建M2_HOME系统变量

5. 添加%JAVA_HOME%\bin;%M2_HOME%\bin;到您的PATH变量

6. 打开命令窗口cmd.校验:mvn -v

7. 如果您有代理,则需要对其进行配置

8. 确保你有.m2/repository(擦除下面的所有文件夹和文件)

9. 如果您打算使用Eclipse,则需要创建 settings.xml

Eclipse中的Maven插件 - Settings.xml文件丢失

你可以在里面看到更多细节
