Suppress deprecation libraries warning

Akka Insights (Cinnamon) supports a range of versions of Akka. As frameworks and library versions expire, they are deprecated in Akka Insights for subsequent removal.

If your application uses a library version whose support has expired, you will see a log warning similar to:

[WARN] [03/08/2021 20:09:10.599] [main-1] [Cinnamon] Lightbend support for Akka 2.5.32 expired on Nov 6, 2020. Support for it in Akka Insights is now deprecated and will be removed in a future release.

Or, in the case of libraries not supported anymore:

[WARN] [03/08/2021 20:11:31.249] [main-1] [Cinnamon]
****************************************************************************
Lightbend Support for Play 2.6.10 expired on Feb 1, 2020
and it IS NOT supported by Akka Insights anymore.

See our Project Support Chart for more information about supported versions:
https://portal.lightbend.com/LightbendPlatform/SupportedProjects#versions
****************************************************************************

The recommended way to get rid of such messages is to update the instrumented library to the latest version.

Suppressing warning messages

Sometimes, you will not be able to do the update in a timely fashion, and in such cases, you can silence the messages until the library is updated to a supported version. To do so, you can add the suppress.deprecations=true parameter to the Akka Insights agent, described in the below sections.

sbt

You can specify the cinnamonArguments sbt setting to provide suppress.deprecations=true to your Akka Insights agent:

cinnamonArguments := "suppress.deprecations=true"

Maven

Under maven, you can modify the <argument> tag that loads the Akka Insights (Cinna agent:

<argument>-javaagent:${project.build.directory}/dependency/cinnamon-agent.jar=suppress.deprecations=true</argument>

Gradle

Under gradle you can modify the jvmArgs attribute that loads the Akka Insights (Cinnamon) agent:

jvmArgs "-javaagent:${configurations.agent.singleFile}=suppress.deprecations=true"
