codacy-coverage-reporter

Multi-language coverage reporter for Codacy https://www.codacy.com

codacy-coverage-reporter will only work with:
  * Java JRE 7 and higher

Setup

Codacy assumes that coverage is previously configured for your project. The official coverage tools we support for Java are JaCoCo and Cobertura.

You can install the coverage reporter by running:

Install jpm

curl https://www.jpm4j.org/install/script | sh

Install codacy-coverage-reporter

jpm install com.codacy:codacy-coverage-reporter:assembly

Updating Codacy

To update Codacy, you will need your project API token. You can find the token in Project -> Settings -> Integrations -> Project API.

Then set it in your terminal, replacing %Project_Token% with your own token:

export CODACY_PROJECT_TOKEN=%Project_Token%

Enterprise

To send coverage in the enterprise version you should:

export CODACY_API_BASE_URL=<Codacy_instance_URL>:16006

Upload coverage

Next, simply run the Codacy reporter. It will find the current commit and send all details to your project dashboard:

codacy-coverage-reporter -l Java -r coverage.xml

Note: You should keep your API token well protected, as it grants owner permissions to your projects.

Java 6

Due to a limitation in Java 6, the plugin is unable to establish a connection to codacy.com. You can run this script after the execution to upload the generated report to Codacy.

Build from source

If you are having any issues with your installation, you can also build the coverage reporter from source.

To make sure you are using the version that you are building, you can remove your previously installed version:

[sudo] jpm remove codacy-coverage-reporter

1- Clone our repository https://github.com/codacy/codacy-coverage-reporter

2- Run the command sbt assembly. This will produce a .jar that you can run in the codacy-coverage-reporter/target/codacy-coverage-reporter-assembly-<version>.jar

3- In the project you want to send the coverage, use the jar. Example:

<path>/java-project$ java -cp ../codacy-coverage-reporter/target/codacy-coverage-reporter-assembly-<version>.jar com.codacy.CodacyCoverageReporter -l Java -r jacoco.xml

Gradle task

A big shout-out to tompahoward, you can create a gradle task as suggested in https://github.com/mountain-pass/hyperstate/commit/857ca93e1c8484c14a5e2da9f0434d3daf3328ce

task uploadCoverageToCodacy(type: JavaExec, dependsOn : jacocoTestReport) {
   main = "com.codacy.CodacyCoverageReporter"
   classpath = configurations.codacy
   args = [
            "-l",
            "Java",
            "-r",
            "${buildDir}/test-results/jacoco/${archivesBaseName}.xml"
           ]
}

task (codacyDepsize) << {
def size = 0;
configurations.codacy.collect { it.length() / (1024 * 1024) }.each { size += it }
println "Total dependencies size: ${Math.round(size * 100) / 100} Mb"

configurations
        .codacy
        .sort { -it.length() }
        .each { println "${it.name} : ${Math.round(it.length() / (1024) * 100) / 100} kb" }
}

task (codacyLocs) << {
    configurations.codacy.each {
        String jarName = it
        println jarName
    }
}

Maven plugin

Thanks to the amazing job of halkeye you can now send your coverage to Codacy using a maven plugin!

Just follow the instructions on his repository.

Troubleshooting

If you receive a Failed to upload report: Not Founderror when running the command, then you'll probably have codacy-coverage-reporter 1.0.3 installed. Make sure you install version 1.0.4, that fixes that error.

Example (issue: #11) :

codacy-coverage-reporter -l Java -r PATH_TO_COVERAGE/coverage.xml
2015-11-20 04:06:58,887 [info]  com.codacy Parsing coverage data... 
2015-11-20 04:06:59,506 [info]  com.codacy Uploading coverage data... 

2015-11-20 04:07:00,639 [error] com.codacy Failed to upload report: Not Found

Even after doing all of the above troubleshooting steps in case you still encounter the same error

2015-11-20 04:07:00,639 [error] com.codacy Failed to upload report: Not Found 

Please try running the command with a --prefix option with path to your code as shown below , it helps to locate the files for which code coverage is desired

codacy-coverage-reporter -l Java -r PATH_TO_COVERAGE/coverage.xml --prefix PATH_TO_THE_DIRECTORY 

Example

codacy-coverage-reporter -l Java -r api/target/site/jacoco/jacoco.xml --prefix api/src/main/java/
