# Importing Bisq into IntelliJ IDEA
Most Bisq contributors use IDEA for development. The following instructions have been tested on IDEA 2021.1.
Most Bisq contributors use IDEA for development. The following instructions have been tested on IDEA 2021.3.
1. Follow the instructions in [build.md](build.md) to clone and build Bisq at the command line.
1. Follow instructions in [build.md](build.md) to clone and build Bisq at the command line
1. Open IDEA
1. Go to `File -> Settings -> Build, Execution, Deployment -> Compiler -> Annotation Processors` and check the `Enable annotation processing` option to enable processing of Lombok annotations (Lombok plugin installed by default since v2020.3)
1. Go to `File -> New -> Project from Existing Sources...` and then select the main Bisq folder to load automatically the related Gradle project
1. If you did not yet setup JDK11 in IntelliJ, go to `File-> Project Structure -> Project` and under the `Project SDK` option locate your JDK11 folder
1. Select JDK 11 for Gradle as well. Go to `File -> Settings -> Build, Execution, Deployment -> Build Tools -> Gradle` and select the JDK11 location for the Gradle JVM value
1. Go to `Build -> Build Project`. Everything should build cleanly
1. Go to `Run > Edit Configurations... -> Plus (+) icon on the top left -> Application` anf then fill the requested fields as shown below, while using as CLI arguments one of those listed in [dev-setup.md](dev-setup.md):
1. If you are inside a loaded Project, go to `File -> Settings -> Build, Execution, Deployment -> Compiler -> Annotation Processors`, else go to `Customize -> All settings... -> Build, Execution, Deployment -> Compiler -> Annotation Processors`, and check the `Enable annotation processing` to enable processing of Lombok annotations (Lombok plugin installed by default since v2020.3)
1. Go to `File -> New -> Project from Existing Sources...` (or `Projects -> Open` from welcome screen) and select the main Bisq folder to automatically load the related Gradle project
1. If you did not yet setup JDK11 in IntelliJ, go to `File -> Project Structure -> Project` and set `SDK` to your JDK11 folder
1. Select JDK11 for Gradle as well: go to `File -> Settings -> Build, Execution, Deployment -> Build Tools -> Gradle` and select the JDK11 location in `Gradle JVM` field
1. Run `Build -> Build Project`, the process should complete correctly
1. Go to `Run > Edit Configurations... -> Plus (+) icon on the top left -> Application` and fill the requested fields as shown below, where `CLI arguments` should be taken from those listed in [dev-setup.md](dev-setup.md) (_Alice_ instance in the example):

9. Now you should be able to run Bisq by clicking on the _Play_ button or via `Run -> Run 'Bisq Desktop'`
10. If you want to debug the application and execute breakpoints, use `Run -> Debug 'Bisq Desktop'`

> TIP: If you encounter compilation errors in IDEA related to the `protobuf.*` classes, it is probably because you didn't build Bisq at the command line as instructed above. You need to run the `generateProto` task in the `other` project. You can do this via the Gradle tool window in IDEA, or you can do it the command line with `./gradlew :other:generateProto`. Once you've done that, run `Build -> Build Project` again and you should have no errors.
