AppMap Maven plugin

Quickstart

First, ensure you have a properly configured appmap.yml in your root project directory. A basic configuration may look like:

# appmap.yml
name: my_organization/my_application

packages:
  # List the packages you'd like to record here.
  - path: com.myorganization.myapplication

  # Individual classes or methods can be chosen as well.
  #
  # - path: com.myorganization.myapplication.MyClass
  # - path: com.myorganization.myapplication.MyClass#myInstanceMethod
  # - path: com.myorganization.myapplication.MyClass.myStaticMethod
  #
  # Optionally, include paths of packages, classes
  # or methods that you'd like to exclude from recording
  #
  # - exclude: com.myorganization.myapplication.util
  # - exclude: com.myorganization.myapplication.MyClass
  # - exclude: com.myorganization.myapplication.MyClass#myInstanceMethod
  # - exclude: com.myorganization.myapplication.MyClass.myStaticMethod

Next, add the following plugin definition to your pom.xml:

<!-- the plugin element goes to build/plugins -->
<!-- AppMap agent, default parameters -->
<plugin>
    <groupId>com.appland</groupId>
    <artifactId>appmap-maven-plugin</artifactId>
    <executions>
        <execution>
            <phase>process-test-classes</phase>
            <goals>
                <goal>prepare-agent</goal>
            </goals>
        </execution>
    </executions>
</plugin>

That's all! The AppMap agent will automatically record your tests when you run mvn test. By default, AppMap files are output to target/appmap.

Using Visual Studio Code? Download the AppMap extension to view AppMap files in your IDE.

About

The AppMap Maven Plugin provides simple method for recording AppMaps in running tests in Maven projects and a seamless integration into CI/CD pipelines. The recording agent requires appmap.yml configuration file, see appmap-java for details.

Plugin goals

  • prepare-agent - adds the AppMap Java agent to the JVM

Plugin configuration

  • configFile Path to the appmap.yml config file. Default: ./appmap.yml
  • outputDirectory Output directory for .appmap.json files. Default: ./target/appmap
  • skip Agent won't record tests when set to true. Default: false
  • debug Enable debug flags as a comma separated list. Accepts: info, hooks, http, locals Default: info
  • debugFile Specify where to output debug logs. Default: target/appmap/agent.log
  • eventValueSize Specifies the length of a value string before truncation occurs. If set to 0, truncation is disabled. Default: 1024

Notes

Configuring Surefire

Some configuration parameters of the Surefire plugin may prevent the appmap plugin from being activated when the tests are run:

  1. forkCount may not be set to 0. Please set it to a value larger than 0 or remove this configuration parameter from pom.xml
  2. If argLine is specified, it must include @{argLine}

Example:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>${maven-surefire-plugin.version}</version>
    <configuration>
        <forkCount>1</forkCount>
        <reuseForks>true</reuseForks>
        <argLine>
            @{argLine} --illegal-access=permit
        </argLine>
    </configuration>
</plugin>

Troubleshooting

I have no target/appmap directory
It's likely that the agent is not running. Double check the prepare-agent goal is being run. If the JVM is being forked at any point, make sure the javaagent argument is being propagated to the new process. Additionally check that the Surefire plugin configuration is not preventing the agent from running. See "Configuring Surefire" for more information.

*.appmap.json files are present, but appear empty or contain little data
Double check your appmap.yml. This usually indicates that the agent is functioning as expected, but no classes or methods referenced in the appmap.yml configuration are being executed. You may need to adjust the packages being recorded. Follow this link for more information: https://github.com/applandinc/appmap-java#configuration

My tests aren't running or I'm seeing The forked VM terminated without properly saying goodbye.
Check the agent log (defaults to target/appmap/agent.log) and/or the Maven Surefire dumpstream (target/surefire-reports/${DATETIME}.dumpstream). This is typically indicative of an invalid appmap.yml configuration.

I have a test failure that only occurs while the agent is attached
Please open an issue at applandinc/appmap-java. Attach a link to the source code or repository (if available), as well as any other relevant information including:

  • the contents of appmap.yml
  • the run command used (such as mvn test)
  • output of the run command
  • any Maven Surefire dumpstreams generated (target/surefire-reports/${DATETIME}.dumpstream)

Running without modifying pom.xml

By specifying the fully-qualified goal, the agent can be run without any additional configuration:

mvn com.appland:appmap-maven-plugin:prepare-agent test
