How do I create a temporary file in Groovy?

Question

In Java there exists the java.io.File.createTempFile function to create temporary files. In Groovy there doesn't seem to exist such a functionality, as this function is missing from the File class. (See: http://docs.groovy-lang.org/latest/html/groovy-jdk/java/io/File.html)

Is there a sane way to create a temporary file or file path in Groovy anyhow or do I need to create one myself (which is not easy to get right if I'm not mistaken)?

Thank you in advance!

Answer 1

File.createTempFile("temp",".tmp").with {     // Include the line below if you want the file to be automatically deleted when the      // JVM exits     // deleteOnExit()      write "Hello world"     println absolutePath } 

Simplified Version

Someone commented that they couldn't figure out how to access the created File, so here's a simpler (but functionally identical) version of the code above.

File file = File.createTempFile("temp",".tmp") // Include the line below if you want the file to be automatically deleted when the  // JVM exits // file.deleteOnExit()  file.write "Hello world" println file.absolutePath

You can use java.io.File.createTempFile() in your Groovy code.

def temp = File.createTempFile('temp', '.txt')  temp.write('test')   println temp.absolutePath
