Question

我认为问题是找不到java或类似的东西。

如果我运行java -version

java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

的Maven：

Apache Maven 3.3.3 (7994120775791599e205a5524ec3e0dfe41d4a06; 2015-04-22T13:57:37+02:00)
Maven home: /Users/rubenortiz/apache-maven-3.3.3
Java version: 1.8.0_45, vendor: Oracle Corporation
Java home: /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home
Default locale: es_ES, platform encoding: UTF-8
OS name: "mac os x", version: "10.10.3", arch: "x86_64", family: "mac"

Answer 1

尝试javac -version ...

因为'也许你是在JRE而不是JDK上运行'......看起来没有编译器。

/ Library / Internet Plug-Ins / JavaAppletPlugin.plugin / Contents / Home是运行java的地方...并且不链接到JDK而是链接到互联网插件

也许安装JDK或更改JAVA_HOME

Answer 2

问题非常简单。您的Java版本查询报告JRE。由于maven错误声明它需要JDK。安装JDK并相应地调整环境变量。

Yosemite上的Maven安装失败：此环境中未提供编译器
