Fix #364

[funkyboy]

@paddybyers Stuck here: https://travis-ci.org/ably/ably-java/jobs/353722078
Fixing is becoming impractical, as in waiting 15m to see the results of a change.

Will follow these instructions and work locally with docker to check what's the problem.

Needed to avoid To run dex in process, the Gradle daemon needs a larger heap. message in Travis.

@paddybyers status so far:

• Android tests are working. API version is 22.
• the gradlew java:* command somehow calls stuff that is related to the android “context”. That leads to https://travis-ci.org/ably/ably-java/jobs/353969106#L2000

Are you sure that's the correct link? I see a bytecode version error there

[funkyboy]

@paddybyers Yes, that's the link I meant. Also this (same error).

I think that when running java:* tests the file /home/travis/build/ably/ably-java/android/build.gradle shouldn't be read and could even not exist.

It might not exist but, since it does, it will be processed. The top-level build.gradle is the thing that's being processed to determine the tasks for the project (which include java-specific tasks). When you say gradle java:xxx then you're asking for that task in that subproject, but it will still process the whole project.

[paddybyers]

LGTM. I added one question.

TBH I think we could collapse all of this into a single commit because there's a bit of back-and-forth in here.

[paddybyers]

Do we still need the --info ?

[funkyboy]

No
