echo command fails on Windows (testProjectExec unit tests)

[brunobowden]

The echo command is used in a number of unit tests, particularly the testProjectExec unit tests in UtilsTest.groovy. This command isn't supported on Windows. The tests are currently disabled on Windows but should be enabled once an alternative is established to the echo command. Current exception:

org.gradle.process.internal.ExecException: A problem occurred starting process 'command 'echo''

@gocursor - it would be a great help to have your insights on this. I don't have a Windows machine, so this is much harder for me to fix. Can you figure out what command can be used to do something like echo for Windows? Echo works on Mac / Linux but for some reason it give the error seen in the description.

Probably the easiest test to work with is testProjectExec_StdOut. Modify line 565 onwards to remove the return and uncomment the line before. The trick will be to replace the ???? section with a command that works. For example:

String executableCmd = 'echo'
if (Utils.isWindowsNoFake()) {
    executableCmd = 'WORKING_COMMAND'
}

i guess echo is not a binary, but a built-in of the shell. try:
executableCmd = 'cmd'
and prepend '/C' as the first arg. (and everything else the same)

That did the trick. I'm close to getting those tests to pass now.
