updateVersion is too fussy about format of properties file

[swpalmer]

I had spaces in my gradle.properties file, e.g.:

version = 0.0.1

This caused updateVersion to fail:

Building > :updateVersion ??> Enter the next version (current one released as [0.0.1]): [0.0.2] :updateVersion FAILED

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':updateVersion'.

  Unable to update version property. Please check file permissions, and ensure property is in "version=0.0.2" format.

• Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

Since this is an allowed practice in properties files it should be supported.

Yep, unfortunately it's unavoidable for now. See issue #27
