Rust submodule gets modified when running build-lf-cli

[edwardalee]

When I run

> build-lf-cli -c

and then do

> git status

I get

	modified:  org.lflang/src/lib/rs/runtime-version.properties

What is this about? Should I commit this?
git diff gives this:

diff --git a/org.lflang/src/lib/rs/runtime-version.properties b/org.lflang/src/lib/rs/runtime-version.properties

I was able to reproduce this and it looks indeed like a bug in build-lf-cli. The behavior is really strange. I have never seen this when using ./gradlew clean buildAll, but on my first try with build-lf-cli my runtime-version.properties also was modified (although to a different version). However, now I cannot reproduce this again... I reverted the change and when I run build-lf-cli it now works as expected... @oowekyala do you have an idea what is going on here?

In any case: the modified file should not be committed.

I think the problem is that the gradle build cache that caches an out-of-date version of the output of git submodule status... I'm working on a fix.

I've seen the same behavior as well, and believe I have ignored the file, but I'm not sure. Will check.
