To find out what the missing dependencies are take the following steps.

-For tor-onion-proxy-library and tor-android-service, replace the following line -in the respective project build file: - $GRADLE_HOME/gradle-4.10.2/bin/gradle --offline --no-daemon -P androidplugin=3.1.0 -Dmaven.repo.local=$gradle_repo assembleRelease -x lint -with - $GRADLE_HOME/gradle-4.10.2/bin/gradle --debug --no-daemon -P androidplugin=3.1.0 assembleRelease -x lint +When calling gradle in the project's build script replace the `--offline` flag +with `--debug` and remove any `-Dmaven.repo.local` arguments.

For the firefox project, comment out the following line in the project's build file:

- export GRADLE_MAVEN_REPOSITORIES="file://$rootdir/[% c('input_files_by_name/gradle-dependencies') %]" + export GRADLE_MAVEN_REPOSITORIES="file://$gradle_repo"

Also modify the gradle flags to include the debug option so the download logs will show up:

export GRADLE_FLAGS="--no-daemon --debug"

-then allow network access during the build by setting -var/container/disable_network/build to 0 in rbm.conf, and rerun the build. +Then allow network access during the build by setting +`var/container/disable_network/build` to `0` in rbm.conf, and rerun the build.
