1.报错信息

  某些war包程序会由于缺乏运行时环境，在maven打包时偶尔出现如下异常:java

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project pa_remove_peel: Compilation failure: Compilation failure:

2.添加运行时环境

  右键项目 -> Build Path -> Configure Build Path -> Libraires -> Add Library -> Server Runtimeapache

  若是列表中没有选项，那么你尚未添加tomcat环境。你能够在菜单栏中的Window-> Preferences 中添加，搜索Server,对应的环境的添加在此处：tomcat
