java - 不支持的 major.minor 版本 51.0 (org/apache/maven/cli/MavenCli) - MAC OS X

Question

这是我的java版本:java -version

java version "1.8.0_20" Java(TM) SE Runtime Environment (build 1.8.0_20-b26) Java HotSpot(TM) 64-Bit Server VM (build 25.20-b23, mixed mode)

还有我的 bash_profile:

JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_20.jdk/Contents/Home
M2_HOME=/Users/michaelkees/apache-maven-3.3.9
M2=/Users/michaelkees/apache-maven-3.3.9/bin
PATH=/Users/michaelkees/apache-maven-3.3.9/bin:/Users/michaelkees/Documents/apache-maven-3.3.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/git/bin:/usr/local/sbin

• 已安装 Maven 3.3.9

当我尝试使用命令时:'mvn -v'

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/apache/maven/cli/MavenCli : Unsupported major.minor version 51.0

Answer 1

转到运行配置并为高于 3.2.X 的 Maven 版本选择 Java 7 或 Java 8Maven 3.3 需要更高的 Java 版本。
