Windows 7 Grails安装

Question

I am working with Groovy & Grails for the first time and having trouble getting the local Windows 7 environment to accept the correct locations of the paths to the bin. Well at least I think after following the www.grails.org\\Installation.

Here is what the prompt feedback is showing:

C:\Groovy Grails\grails-1.3.7>gradlew

ERROR: JAVA_HOME might be set to an invalid directory: C:\Program Files\Java\jdk
1.7.0_03\bin;

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation if there are problems.

The system cannot find the path specified.

Any suggestions to get going in grails?

Answer 1

take off the /bin, just use: C:\\Program Files\\Java\\jdk 1.7.0_03

never tried to build grails. here what happened:

R:\dev\grails-2.0.1>gradlew --stacktrace

FAILURE: Build failed with an exception.

* Where:
Script 'R:\dev\grails-2.0.1\gradle\assemble.gradle' line: 56

* What went wrong:
A problem occurred evaluating script.
Cause: Could not find property 'org' on root project 'grails-2.0.1'.

* Try:
Run with --info or --debug option to get more log output.

* Exception is:

Answer 2

I'm running Grails on a Windows 7 machine and had no problems. My environment variables look like this:

JAVA_HOME=C:\\Program Files\\Java\\jdk1.6.0_25

GRAILS_HOME=C:\\grails-1.3.8

No problems getting it to run. But it runs horribly slowly, which it did not do on my xp machine.

Answer 3

尝试将您的JAVA_HOME设置为“ C：\\ Program Files \\ Java \\ jre7”，即在Java目录中的jre文件夹而不是JDK文件夹中。（请参阅此 SO帖子）这对我有用。

Answer 4

You might be adding quotes to the RC file.

This is the contents of my %USERPROFILE%\\\\.groovy\\preinit.bat :

set GROOVY_HOME=C:\Path\To\Groovy<br/>
set JAVA_HOME=C:\Program Files\Java\jdk1.8.0_92
