Subproject's build/install different distribution

Hi

I am wondering why gradlew install is different than gradlew build. Any idea why the install task is not distributed to subprojects as the build task

Z:\git\EGC>gradlew build
Starting a Gradle Daemon (subsequent builds will be faster)

onment variable 'INCLUDE'.

BUILD SUCCESSFUL

Z:\git\EGC>gradlew install

FAILURE: Build failed with an exception.

* What went wrong:
Task 'install' is ambiguous in root project 'EGC'. Candidates are: 'installEG1Executable', 'installEG2Executable', 'installEG3Execut
able', 'installEG4Executable'.

* Try:
Run gradlew tasks to get a list of available tasks. Run with --stacktrace option to get the stack trace. Run with --info or --debug
option to get more log output.
