[PATCH] Fix gradlew completion

[Shohei YOSHIDA <syohex@xxxxxxxxx>]

gradlew is not usually in the PATH so the command to retrieve tasks would fail
due to 'command not found'. So it should execute './gradlew' instead of 'gradle'
if service is gradlew and there is an executable file './gradlew' in current
directory
