I am developing Eclipse plugin to run Gradle from Eclipse just as an application (using Eclipse LaunchConfiguration). But even after setting JAVA_HOME and GRADLE_HOME for this new process, it finishes with error. Below is what I got by passing additional --debug --stacktrace

So for what file Access is denied and how to discover that?

Eclipse is launched with JRE 1.7 on Win32

Gradle 1.10. Of course the same works from command line shell.

The way to discover this is to look into the Gradle codebase. The IOException is thrown by the following line:

File file = File.createTempFile("gradle_fs_probing", null, null);

So apparently, the Java process isn't able to create a temporary file. Perhaps this is a file permission issue.

  • Thank so much. The effort continues at http://stackoverflow.com/questions/21360995/processes-launched-from-java-with-runtime-getruntime-exec-cant-get-access-t – Paul Verest Jan 26 '14 at 10:15
  • I think you must set the env variable for temp directory. For windows set TEMP and/ TMP variable. – Duff May 29 '18 at 10:18

In my case the same problem was caused by not defining the default environment properties (Environment was Eclipse & Windows). Then, gradle is missing some properties e.g. for temp directory.

So this works:

def myenv = [ "JAVA_HOME=./jdk" ]
def env = System.getenv().collect { k, v -> "$k=$v" } + myenv
def proc = "./gradlew".execute(env, new File('.'))

while this might not work

def myenv = [ "JAVA_HOME=.\\jdk" ]
def proc = "./gradlew".execute(myenv, new File('.'))
