This document describes how to import Haveno into an integrated development environment (IDE).
## Importing Haveno into Eclipse IDE
The following steps describe how to import Haveno into Eclipse IDE for development. You can also develop using [IntelliJ IDEA](#importing-haveno-into-intellij-idea) or VSCode if you prefer.
> Note: Use default values unless specified otherwise.
1. Download and run the [Eclipse](https://www.eclipse.org/downloads/) installer.
2. Select "Eclipse IDE for Enterprise Java and Web Developers" to install.
3. Launch an eclipse workspace and close out of the welcome screen.
4. [Download](https://search.maven.org/search?q=g:org.projectlombok%20AND%20a:lombok&core=gav) the latest version of the lombok jar.
5. Run lombok jar, e.g.: `java -jar ~/Downloads/lombok-1.18.22.jar`.
6. Follow prompts to install lombok to your Eclipse installation.
7. Restart Eclipse.
8. File > Import... > Existing Gradle Project.
9. Select the location of "haveno" project, e.g. ~/git/haveno.
10. Advance to finish importing haveno project.
11. File > Import... > Existing Projects into Workspace.
12. Select the location of "haveno-ui-poc" project, e.g. ~git/haveno-ui-poc.
13. Advance to finish importing haveno-ui-poc project.
You are now ready to make, run, and test changes to the Haveno project!
## Importing Haveno into IntelliJ IDEA
> Note: These instructions are outdated and for Bisq.
Most Bisq contributors use IDEA for development. The following instructions have been tested on IDEA 2021.1.
1. Follow the 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):
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.
