sbt plugin for uploading Scala code coverage to Codacy https://www.codacy.com
sbt-codacy-coverage will only work with:
- sbt 0.13.5 and higher
- Java JRE 7 and higher
Codacy assumes that coverage is previously configured for your project. As an example, we will configure a Scala project with the
scoverage sbt plugin.
To start, add the
scoverage and Codacy sbt plugins into your plugins.sbt file:
resolvers += "Typesafe Repository" at "https://repo.typesafe.com/typesafe/releases/" addSbtPlugin("org.scoverage" % "sbt-scoverage" % "1.5.1") addSbtPlugin("com.codacy" % "sbt-codacy-coverage" % "<latest-version>")
Check latest version in https://maven-badges.herokuapp.com/maven-central/com.codacy/sbt-codacy-coverage
Coverage should now be enabled for your project. To run the tests and create coverage files, type in your terminal:
sbt clean coverage test
This will create coverage reports for all your tests in your project. In order to export scoverage report files into cobertura compatible files, just type:
This will create the required report format for the Codacy plugin to read. If you have sub-projects within your project, you will want to aggregate all reports into one by running:
To update Codacy, you will need your project integration token. You can find the token in Project -> Settings -> Integrations -> Add Integration -> Project API.
Then set it in your terminal, replacing %Project_Token% with your own token:
Note: You should keep your API token well protected, as it grants owner permissions to your projects.
Next, simply run the Codacy sbt plugin. It will find the current commit and send all details to your project dashboard:
Note: To send coverage in the enterprise version you should:
Codacy automatically detects the CommitUUID from several sources:
- If it finds a git directory it will get current commit.
- You may want to enforce a specific commitUUID with:
sbt 'set codacyCommit := "mycommituuid"' codacyCoverage
Configure your build server
After setting up and testing the coverage, you're ready to setup your build server to automate your process. Simply replace the step used to run your tests with the process done so far, shown here for brevity sake:
sbt clean coverage test sbt coverageReport sbt coverageAggregate sbt codacyCoverage
Failing tests can be caused by the usage of macros in Scala 2.10. Consider upgrading to Scala 2.11 for full macro support.
- Builds from forks are failing on Coverage?
If you are using an automated CI that also runs builds from forks but does not have access to the project token to send coverage you should protect the coverage step in your configuration to avoid the build failure.
- Failing to send coverage
Failed to upload data. Reason: not found
This issue is usually related to bad authentication. Make sure you are using the correct token. Most time you will want to use the Project API Token as described in Updating Codacy.
If you decide to use the Account API Token, you will need to provide extra details about your project. You need to make sure to provide the project owner username and the project name on Codacy as part of the identification when pushing coverage.
if [[ -n "$CODACY_PROJECT_TOKEN" ]]; then sbt codacyCoverage; else echo "Skipped coverage reporting since no token was found"; fi
Due to a limitation in Java 6, the plugin is unable to establish a connection to codacy.com. You can run this script after
sbt codacyCoverage to upload the generated report to Codacy.
