离子构建失败：JAVA_HOME无效

Question

I wanted to start my first build with ionic. But the Build fails very soon with the following error:

Running command: E:\Apps\ASV\Node\node.exe E:\Apps\ASV\Code\MyASV\hooks\after_prepare\010_add_platform_class.js E:\Apps\ASV\Code\MyASV
add to body class: platform-android
Error: Failed to run "java -version", make sure that you have a JDK installed.
You can get it from: http://www.oracle.com/technetwork/java/javase/downloads.
Your JAVA_HOME is invalid: C:\Program Files\java\jdk1.8.0_77

I tried several things over the past hour to fix this. I deinstalled all Java related stuff, reinstalled it, set the JAVA_HOME several times to the jdk path, added %JAVA_HOME%\\bin to the path-variable, but nothing fixed it. Currently my JAVA_HOME, which i had to create manually, looks like this at the moment:

C:\Program Files\Java\jdk1.8.0_77

Please note that this path is different to the one in the error message. The 'Java' is written in lowercase and in uppercase, I don't know if this is relevant. Also changing this JAVA_HOME variable and then trying a rebuild gives the same error, the changed variable seems to have no effect on the one ionic uses.

How can I fix this? What exactly is going wrong?

Answer 1

Okay, i fixed it. The Error

Your JAVA_HOME is invalid: C:\Program Files\java\jdk1.7.0_79

Is quite irritating. The error was that the PATH-variable missed an entry like

C:\Program Files\Java\jdk1.7.0_79\bin

Somehow

%JAVA_HOME%\bin

still causes the error.

Answer 2

您将需要编辑框的环境变量，以将JAVA_HOME指向当前的jdk bin /目录

Answer 3

it should be pointing to JDK\\bin folder , usually C:\\ProgramFiles\\Java\\jdk*\\bin directory.

I recently tried in my new windows PC and gone through same issue.
