		MOD=$1

		cat <<EOF

		$MOD is a java_library that generates a jar file which must not be accessed
		from outside the mainline module that provides it. If you are seeing this
		message it means that you are incorrectly attempting to use the jar file
		from a java_import prebuilt of $MOD.

		This is most likely due to an incorrect dependency on $MOD in an Android.mk
		or Android.bp file. Please remove that dependency and replace with
		something more appropriate, e.g. a dependency on an API provided by the
		module.

		If you do not know where the extraneous dependency was added then you can
		run the following command to find a list of all the paths from the target
		which you are trying to build to the target which produced this error.

		prebuilts/build-tools/linux-x86/bin/ninja -f out/combined-\${TARGET_PRODUCT}.ninja -t path <target> <invalid-jar>

		Where <target> is the build target you specified on the command line which
		produces this error and <invalid-jar> is the rule that failed with this
		message. If you are specifying multiple build targets then you will need to
		run the above command for every target until you find the cause.

		The command will output one (of the possibly many) dependency paths from
		<target> to <invalid-jar>, one file/phony target per line. e.g. it may
		output something like this:

		....
		out/soong/.intermediates/acme/broken/android_common/combined/broken.jar
		out/soong/.intermediates/prebuilts/module_sdk/art/current/sdk/prebuilt_core-libart/android_common/combined/core-libart.jar
		out/soong/.intermediates/prebuilts/module_sdk/art/current/sdk/art-module-sdk_core-libart-error/gen/this-file-will-never-be-created.jar

		The last line is the failing target, the second to last line is a dependency
		from the core-libart java_import onto the failing target, the third to last
		line is the source of the dependency so you should look in acme/Android.bp
		file for the "broken" module.
