윈도우에서 Grails 2.1.1 설치 후 JAVA_HOME 에러가 나는 경우

 

윈도우에서 Grails 2.1.1 을 설치한 후, 한경변수 GRAILS_HOME, JAVA_HOME, PATH 가 모두 잡혔는데도 불구하고 "rails create-app" 명령시 에러

ERROR: JAVA_HOME is set to an invalid directory: C:\Program Files\Java\jre7

Please set the JAVA_HOME variable in your environment to match the
location of your Java installation.

가 나는 경우가 있다. (리눅스/유닉스에서는 이런 경우가 없음 )

이럴 때는 startGrails.bat 파일을 텍스트 편집기로 열어서 42번째 줄

%COMMAND_COM% /C DIR "%JAVA_HOME%" 2>&1 | %FIND_EXE% /I /C "%JAVA_HOME%" >nul

을

@rem %COMMAND_COM% /C DIR "%JAVA_HOME%" 2>&1 | %FIND_EXE% /I /C "%JAVA_HOME%" >nul

로 고쳐서 주석처리 한다. 그러면 "grails create-app" 명령이 잘 된다.

다음은 C:\test\grails 폴더에서 helloworld 애플리케이션을 성공적으로 생성한 경우의 출력이다.

C:\test\grails> grails create-app helloworld
