- How mature is it?
-
The code was ported from Apache Ant and extensively
tested on various platforms. So there is no reason not to use it and it is very likely
better than any home-grown library.

- How do I create a complex command line using single and double quotes?
-
It is recommended to use CommandLine.addArgument() instead of CommandLine.parse(). Using
CommandLine.parse() the implementation tries to figure out the correct quoting using your
arguments and file names containing spaces. With CommandLine.addArgument() you can
enable/disable quoting depending on your requirements. Having said that this is the
recommended approach using Ant anyway.

- Are child processes automatically killed?
-
This functionality is largely depend on the operating system - on Unix it works
mostly and under Windows not at all (see
Bug 4770092). In terms of stability and cross-platform support try to start your applications directly and
avoid various wrapper scripts.

- Does commons-exec support java-gcj?
-
Well - one out of 55 regression tests fails. The
EnvironmentUtilTest.testGetProcEnvironment() test fails because it detects no environment
variables for the current process but there must be one since we require JAVA_HOME to be
set. Not sure if this is a plain bug in java-gcj-4.2.1 or requires a work around in
commons-exec

- Why is the regression test broken on my Unix box
-
Please check if the shell scripts under "./src/test/script" are executable - assuming
that they are not executable the "testExecute*" and "testExecuteAsync*" test will
fail. We try very hard to keep the executable bit but they have somehow the tendency
to be lost ...
