为 make OS X 设置 JDK 路径

Question

I am trying to build Android AOSP on Mac OS X 10.13.6

When running make it outputs

build/core/config.mk:601: *** Error: could not find jdk tools.jar at /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/../lib/tools.jar, please check if your JDK was installed correctly.  Stop.

JAVA_HOME and ANDROID_JAVA_HOME are both set to the directory of my JDK installation:

/Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home

I know that the files under System/Library/.../Commands are stubs pointing to the correct JDK installation but make tries to find the tools.jar in this directory, too.

Is there a way to tell make to search in the right directory?

EDIT

Error appears in config.mk:601

# We may not have the right JAVA_HOME/PATH set up yet when this is run from envsetup.sh.
ifneq ($(CALLED_FROM_SETUP),true)
HOST_JDK_TOOLS_JAR:= $(shell $(BUILD_SYSTEM)/find-jdk-tools-jar.sh)

ifneq ($(HOST_JDK_TOOLS_JAR),)
ifeq ($(wildcard $(HOST_JDK_TOOLS_JAR)),)
$(error Error: could not find jdk tools.jar at $(HOST_JDK_TOOLS_JAR), 
please check if your JDK was installed correctly)
endif
endif

But when running find-jdk-tools-jar.sh it outputs the correct path, where the tools.jar is indeed located. So make uses some other fallback?

On OSX, /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/ is not where JDK root is. JDK install home is usually /Library/Java/JavaVirtualMachines/jdk[whatever you have installed].jdk/Contents/Home

You need to configure your JAVA_HOME correctly.
