Run the command />which javato determine where the javacommand is coming from on the path.
运行命令/>which java以确定java命令在路径上的来源。
You either need to change to put jdk 1.8 on the path or use the fully qualified path to the javaexecutable.
您需要更改以将 jdk 1.8 放在路径上，或者使用java可执行文件的完全限定路径。

我遇到了同样的错误，虽然 java 版本正确设置为 8，但我的 JAVA_HOME env var 仍然设置为 7。

执行它为我修复了它：
export JAVA_HOME=/usr/lib/jvm/java-8-oracle
