The downloaded files do not have the correct extensions

[Bencodes]

rules_jvm_external doesn't append the proper file extensions to the downloaded files which prevents direct consumption. This can be worked around by making a copy that has the correct file extension before passing them to java_import and aar_import.

Example: java_import asserts that the provided inputs for both jars and srcjar have .java as it's file extension. aar_import mirrors this behavior by asserting that the provided input has .aar as it's file extension.

java_import(
    name = "example_java_import",
	# Produces an error in Bazel
    jars = ["@org_jetbrains_kotlinx_kotlinx_coroutines_core_jvm_1_6_1//file"],
	# Produces an error in Bazel
    srcjar = "@org_jetbrains_kotlinx_kotlinx_coroutines_core_jvm_jar_sources_1_6_1//file:file",
)

aar_import(
    name = "example_aar_import",
	# Produces an error in Bazel
    aar = "@androidx_room_room_runtime_2_4_2//file",
	# Produces an error in Bazel
    srcjar = "@androidx_room_room_runtime_aar_sources_2_4_2//file",
)
