Maven忽略OSX上的JAVA_主页？

出于某种原因，Maven忽略了OSX上的JAVA_主页

我最近从Java8Build11升级到Java8Build25，由于25中的错误修复，我删除了11

我已经更新了

JAVA\u HOME

：

:~ > echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home

java

和

javac

都报告了正确的版本：

:~ > java -version
java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)

:~ > javac -version
javac 1.8.0_25

libexec

是否正确：

:~ > /usr/libexec/java_home 
/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home

:~ > ls -la /System/Library/Frameworks/JavaVM.framework/Versions/

当前JDK符号链接正确：

lrwxr-xr-x   1 root  wheel    58B Nov 19 14:35 CurrentJDK@ -> /Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents

但Maven仍在努力达到1.8.0_11：

:~ > mvn -version
Error: JAVA_HOME is not defined correctly.
  We cannot execute /Library/Java/JavaVirtualMachines/jdk1.8.0_11.jdk/Contents/Home/bin/java

运行OSX小牛

知道Maven为什么忽略JAVA_HOME吗？

一位同事告诉我问题出在哪里。他不想要代表积分，所以我只是为任何可能通过谷歌找到这一点的人发布答案

解决办法是

export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home

在

显然，不管出于什么原因，maven都有自己的配置文件。使用上述值创建上述文件立即修复了问题：

:~ > mvn -version
Apache Maven 3.2.3 (33f8c3e1027c3ddde99d3cdebad2656a31e8fdf4; 2014-08-11T16:58:10-04:00)
Maven home: /usr/local/Cellar/maven/3.2.3/libexec
Java version: 1.8.0_25, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.9.5", arch: "x86_64", family: "mac"

---

我通过添加

export JAVA_HOME=“$（/usr/libexec/JAVA_HOME）”

到

~/.mavenrc

---

苹果建议使用

/usr/libexec/java_home

而不是使用java的整个路径

非常有用的信息，这只适用于maven3，对吗？我无法回答，因为我没有在mac上运行pre-maven3在mac sierra上用maven 2.2.1修复了这个问题，我找不到

~/.mavenrc

。我必须创建它吗？如果它不在那里，那么是的，创建它。
