maven构建常见错误

Caused by: org.apache.maven.plugin.PluginExecutionException:

Execution default-cli of goal org.apache.tomcat.maven:tomcat7-maven-plugin:2.1:run failed: Plugin org.apache.tomcat.maven:tomcat7-maven-plugin:2.1 or one of its dependencies could not be resolved: Failed to collect dependencies at org.apache.tomcat.maven:tomcat7-maven-plugin:jar:2.1 -> org.apache.tomcat.embed:tomcat-embed-core:jar:7.0.37

相关jar包没有下载好，重新输入 mvn tomcat7:run 命令

org.apache.jasper.JasperException: Unable to compile class for JSP:

tomcat7以下的版本不支持 jdk8

更改pom 中的插件配置

出现其他故障 ， 将 users\ 用户名\ .m2 目录删除 重新下载 mvn help：System
或者 重新编译 mvn clean|| mvn test|| mvn tomcat7:run
