aosp build issue with "error: overriding commands for target...com.google.vr.platform.jar"

[supergps1]

I am trying to build Android-tv with opengapps::nano for hikey960
AOSP is master branch latest on 19May2019.
I have copied opengapps/aosp_build to vendor/opengapps/build
I have copied nezor/all, nezor/arm and nezor/arm64 to vendor/opengapps/sources

I added fix for #217 (using /bin/ls). Additionally I had to use /usr/bin/lzip instead of lzip in find_apk.sh

Build now fails with following log:

This is a bit out of my depth right now. Any help is appreciated.

Build succeeds when opengapps is not included.

[supergps1]

Apparently frameworks/base/vr/ has build instructions for java library com.google.vr.platform, so for now, I deleted com.google.vr.platform.jar files from vendor/opengapps/sources/all/framework/27 and vendor/opengapps/sources/all/framework/28
This allows the build to proceed from this point, but I am not sure if there are any adverse effects.
I am also not yet sure if build will complete after this change.

I am also having the same issue. Any workarounds? Mu build is successful but it doesn't boot
