   Hi @Code0x58,
   
   Firstly, thanks to having a look this.
   
   It looks like _no matching toolchains found_ from latest travis log:
   ```
   (18:43:50) ERROR: While resolving toolchains for target //heron/api/src/scala:api-scala: no matching toolchains found for types @io_bazel_rules_scala//scala:toolchain_type
   (18:43:51) ERROR: Analysis of target '//heron/api/src/scala:api-scala' failed; build aborted: no matching toolchains found for types @io_bazel_rules_scala//scala:toolchain_type
   ```
   
   From bazel doc, we can try setting default toolchain if no concern.
   ```
   # WORKSPACE
   # register default scala toolchain
   load("@io_bazel_rules_scala//scala:toolchains.bzl", "scala_register_toolchains")
   scala_register_toolchains()
   ```
