Maven Install报错：Perhaps you are

所遇问题：

英文描述：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.5.1:compile (default-compile) on project busiservice: Compilation failure
[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

中文描述：此环境中未提供编译器，你可能使用jre运行而不是jdk。
引发原因：Eclipse默认在jre上运行，maven install 编译需要jdk中的编译器，而jre中并没有
问题解决：

Window->Preferences
Java->Installed Rres->Add
Directory...
jdk->ok
Java->Installed JREs->Execution Environments->JavaSE-1.7->jdk1.x
Java->Installed JREs->Execution Environments->JavaSE-1.8->jdk1.x
maven->install(编译成功)
