[GRADLE-1577] JavaExec task doesn't seem to handle spaces in the executable path or in classpath. Created: 27/May/11  Updated: 10/Feb/17  Resolved: 10/Feb/17

 Description   

I have the following JavaExec task set up:

task(gwtCompile, dependsOn: classes, type: JavaExec)

{ main = 'com.google.gwt.dev.Compiler' jvmArgs = ['-Xmx512M'] classpath files(file('src')) classpath sourceSets.main.runtimeClasspath args "-war $buildDir" args '-logLevel INFO' args 'com.acme.application.GwtModule' }

The error I get from running this through the JavaExec task is:

Unknown argument: -war C:\application\client\build

I figured out the command line wasn't getting executed correctly because of spaces in the path to the java.exe (e.g. C:\Program Files\Java\jdk1.6.0_20\bin) and where the jars are in the gradle cache under C:\Documents and Settings

I printed out the command line from gradle using below:

gwtCompile.doFirst {
println "command line: ${gwtCompile.commandLine}"
println "executable: ${gwtCompile.executable}"
}

Dumped this into a Windows bat file and double quoted around the paths that had spaces and was able to execute the task as I expected it to work.

Thanks,
jas

I made a mistake on the environment. I am running this on Windows XP.
