+If you are using a [Maven task](../tasks/build/maven.md), make sure to also pass the `MAVEN_OPTS` variable because it gets overwritten otherwise:
+
+```yaml
+- task: Maven@3
+  inputs:
+    mavenPomFile: 'pom.xml'
+    mavenOptions: '-Xmx3072m $(MAVEN_OPTS)'
+```

 ## .NET/NuGet
 
 If you use `PackageReferences` to manage NuGet dependencies directly within your project file and have `packages.lock.json` file(s), you can enable caching by setting the `NUGET_PACKAGES` environment variable to a path under `$(Pipeline.Workspace)` and caching this directory.
