ERROR: Unknown host CPU architecture: arm64
reason
There are two possible reasons for the above error:
- The JDK version of the current device is not JDK8 (1.8.x), Cocos2.4.9 only supports JDK8
- Currently using the openjdk Jre environment instead of Java SE
solution
Go to the official website of Java Downloads to download the complete JDK8 version.
missing tools.jar
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':libcocos2dx:compileDebugJavaWithJavac'.
> Could not find tools.jar. Please check that /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home contains a valid JDK installation.
This problem occurs on MAC computers, and there will be a plug-in when JDK8 is installed on the device. The device will use the plug-in to JDK environment by default.
The plug-in to the JDK lacks tools.jar.
solution
Find your JDK8安装目录/Contents/Home/libcopy of tools.jar
in the default /Library/Java/JavaVirtualMachines
copy tools.jar paste to/Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/lib
