When defining an `Exec` task, is it possible to redirect both `standardOutput` and `errorOutput` to the same file, so they are interleaved as they happen? I tried this:

```
def logFile = file("${temporaryDir}/output.txt")
standardOutput = logFile.newOutputStream()
errorOutput = standardOutput

```

This sometimes seems to work and sometimes fails with `java.io.IOException: Stream Closed`. For now I’m sending the two streams to two separate files, but is there any (simple) way to use only one?

Instead of using `java.io.OutputStream`, try using `java.io.FileOutputStream`. It overrides its `finalize()` method to only call `close()` after all references to it are removed.
