sbt-codacy-coverage fails to upload data from Travis CI
<p>I have set up a Scala/SBT project with Travis CI and Codacy integration. The sources are visible at <a href="https://github.com/guilgaly/itunes-dap-sync" rel="nofollow noreferrer">https://github.com/guilgaly/itunes-dap-sync</a>.</p>

<p>I wanted to be able to view a code coverage report in Codacy, so I added the following SBT plugins:</p>

<pre><code>addSbtPlugin("org.scoverage" % "sbt-scoverage" % "1.5.0")
addSbtPlugin("com.codacy" % "sbt-codacy-coverage" % "1.3.7")
</code></pre>

<p>And I was able to upload coverage data to Codacy with the following commands:</p>

<pre><code>export CODACY_PROJECT_TOKEN=&lt;my token&gt;
sbt clean coverage test
sbt coverageReport
sbt coverageAggregate
sbt codacyCoverage
</code></pre>

<p>To automatically upload coverage data from the Travis CI build, I set up the <code>CODACY_PROJECT_TOKEN</code> environment variable for the project, and used the following <code>.travis.yml</code> configuration:</p>

<pre><code>language: scala
scala:
  - 2.12.1
jdk:
  - oraclejdk8
script:
  - sbt clean coverage test
after_success:
  - sbt coverageReport
  - sbt coverageAggregate
  - sbt codacyCoverage
</code></pre>

<p>But in the Travis CI build log, I see that <code>codacyCoverage</code> fails, with <code>java.lang.RuntimeException: Failed to upload data. Reason: Request handler not found: /2.0/coverage//scala</code>:</p>

<p>Any idea idea what might cause this issue, visible in the Travis CI build but not in my local SBT build?</p>
