No compiler is provided in this environment. Perhaps you are running on a JR

maven编译项目时出错，提示信息如下：

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

[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

解决方案：

1，在eclipse的菜单中，进入 Window > Preferences > Java > Installed JREs ->Add ->Standard VM

jre home 选择jdk安装目录，然后选中

2，右键项目build path

jdk是开发工具

jre是运行环境

编译用的都是jdk的resources嘛，开发时不能只有运行库，应该具备开发库，就是这个意思。

另外***is not a servlet的错

servlet和jsp的作用域加上就可以
