# Maven. Runner

Use this page to configure settings for the external Maven that will be used to run goals.

| Item | Description |
| --- | --- |
| Delegate IDE build/run actions to Maven | Select this checkbox to build, run, and debug code through Maven. It might be helpful if you have a configuration that changes the compilation on the fly, or your build generates an artifact with a custom layout.   For more information, refer to [Maven projects](delegate-build-and-run-actions-to-maven.html#delegate_to_maven).     |
| VM Options | Specify VM options that will be passed to the selected JRE.     When specifying JVM options, follow these rules:       * Use spaces to separate individual options, for example, `-client -ea -Xmx1024m`.    * If an option includes spaces, enclose the spaces or the argument that contains spaces in double quotes, for example, `some" "arg` or `"some arg"`.    * If an option includes double quotes (as part of the argument), escape the double quotes using backslashes, for example, `-Dmy.prop=\"quoted_value\"`.    * You can pass environment variable values to custom Java properties. For example, if you define a variable `MY_ENV_VAR`, you can pass it to the `foo` property as follows: ``` -Dfoo=${MY_ENV_VAR} ```     |
| JRE | Select the [JRE](maven-support.html#maven_runner_jdk) that will be used to run the Maven goals. |
| Environment variables | This field lets you set custom environment variables on the project level for running maven goals.   Specify an environment variable, for example, `${env.JAVA_VERSION}` in the pom.xml of your project.     ![Environment variable in the pom.xml](https://resources.jetbrains.com.cn/help/img/idea/2026.2/env_var_pom.png)   Click Browse ![the Browse button](https://resources.jetbrains.com.cn/help/img/idea/2026.2/app.general.ellipsis.svg) to open the Environment Variables dialog, where you can set a value for the specified environment variable.
