Maven报错

Posted 2020-09-28 doStudying

今天把项目down下来,项目,报错maven clean ,install 没解决,然后jdk版本也对,maven,M2-HOME安装没有问题.

问题标志为maven install 下的jar包不完全

项目运行报错:

Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:2.8:copy-dependencies (copy-dependencies) on project operationPlat-if: Execution copy-dependencies of goal org.apache.maven.plugins:maven-dependency-plugin:2.8:copy-dependencies failed: Unable to load the mojo \'copy-dependencies\' in the plugin \'org.apache.maven.plugins:maven-dependency-plugin:2.8\'. A required class is missing: org/codehaus/plexus/archiver/ArchiverException

重新配置maven settings.xml发现报错

Unable to update index for nexus|http://10.10.66.33:8082/nexus/content/groups/public-snapshots/

 

安装路径不能有空格,不能有中文.

解决方法 :

1. 确保正确安装maven。(安装路径不能有空格,不能有中文)

2. 确保相关的环境变量存在（M2_HOME、 MAVEN_HOME,JAVA_HOME等）。

3. 确保settings.xml中的库目录指向正确的地址,下载地址也得保证正确.

 

4. 如果还是不行就完全删掉maven，从第一条开始做起.
