在Mac上构建openjdk“未正确定义JAVA_HOME"； [英] build openjdk on mac "JAVA_HOME is not defined correctly"

问题描述

我正在MAC上构建openjdk并遇到这样的问题:

I am building openjdk on MAC and facing a problem like this:

Error: JAVA_HOME is not defined correctly.
We cannot execute /NO_BOOTDIR/bin/java

我的Mac的操作系统是10.10.2.

the OS of my mac is 10.10.2.

openjdk是

openjdk-7u40-fcs-src-b43-26_aug_2013

ALT_BOOTDIR

the ALT_BOOTDIR

export ALT_BOOTDIR=/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home

$ JAVA_HOME

the $JAVA_HOME

echo $JAVA_HOME
/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home

当我设置JAVA_HOME并运行"make sanity"时，错误是这样的:

when I set JAVA_HOME and run 'make sanity', the error is like this:

ERROR: Your JAVA_HOME environment variable is set.  This will
   most likely cause the build to fail.  Please unset it
   and start your build again.

所以我必须取消设置，无论是否取消设置，都会出现错误.

so I have to unset it and no matter I unset it or not, the error appears.

有什么想法吗?

思考.

推荐答案

在设置路径之前，请通过检查目录

Before setting the path make sure that java is installed by checking the directory

/Library/Java/JavaVirtualMachines/<version>.jdk/Contents/Home

然后在.bashrc或.bash_profile

JAVA_HOME=/Library/Java/JavaVirtualMachines/<version>.jdk/Contents/Home
export JAVA_HOME

如果缺少OpenJDK，则可以通过酿造

If it OpenJDK is missing you can install it through brew

brew tap AdoptOpenJDK/openjdk
brew cask install adoptopenjdk8

在/usr/bin到java和javac
