maven报错
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-install-plugin:2.3.1:install (default-install) on project Upload: Execution default-install of goal org.apache.maven.plugins:maven-install-plugin:2.3.1:install failed: Unable to load the mojo 'install' in the plugin 'org.apache.maven.plugins:maven-install-plugin:2.3.1'. A required class is missing: org/codehaus/plexus/digest/DigesterException
解决方案：
将maven本地库全部删除，执行 maven clear install 命令即可
