Bug from 1.9.6 to 2.1.9 when using a genrule to execute a kt_jvm_binary

[dnkoutso]

We are seeing a bug that could be related to our repo configuration.

Its a bit difficult to provide a sample from our monorepo but here's the gist:

    kt_jvm_binary(
        name = name + "_swiftpoetgen_kt",
        srcs = srcs,
        main_class = main_class,
        deps = ["@maven//:io_outfoxx_swiftpoet"],
    )

    genrule(
        name = name + "_swiftpoetgen.swift",
        srcs = [],
        outs = outs,
        cmd = "$(location {}) $(OUTS)".format(name + "_swiftpoetgen_kt"),
        tools = [name + "_swiftpoetgen_kt"],
    )

Invoking this in 1.9.6 we see the launcher script template with:

# Set JAVABIN to the path to the JVM launcher.
JAVABIN=external/rules_java~~toolchains~local_jdk/bin/java

which works correctly but with 2.1.x:

# Set JAVABIN to the path to the JVM launcher.
JAVABIN=../rules_java~~toolchains~local_jdk/bin/java

This ends up failing with this error message:

line 409: exec: /<redacted>/_main/../rules_java~~toolchains~remotejdk11_macos_aarch64/bin/java: cannot execute: No such file or directory

Could it be related to #1244?

Thanks in advance!

Should be fixed with #1380
