I was following as tutorial when I faced this problem.

abt java & mvn

C:mvn>echo %JAVA_HOME% 
C:mvn>echo %JRE_HOME%
C:mvn>echo %MAVEN_HOME% yields

C:Program FilesJavajdk1.7.0_51
C:Program FilesJavajre7
C:apache-maven-3.0.4

推荐答案

您已将 %JAVA_HOME 设置为 jdk 1.7，但您正在尝试使用 1.8 进行编译.安装 jdk 1.8 并确保您的 %JAVA_HOME 指向该版本或将目标版本降至 1.7.

You have set your %JAVA_HOME to jdk 1.7, but you are trying to compile using 1.8. Install jdk 1.8 and make sure your %JAVA_HOME points to that or drop the target release to 1.7.

无效的目标版本:1.8

invalid target release: 1.8

目标版本是指jdk版本.

The target release refers to the jdk version.
