  1. In the `Import Project from Gradle` screen, check the `Use auto-import` option and click `OK`
  1. When prompted whether to overwrite the existing `.idea` directory, click `Yes` (This step was not required with 2019.2 but is kept here in case you are running an older version)
  1. In the `Project` tool window, right click on the root-level `.idea` folder, select `Git->Revert...` and click OK in the dialog that appears (to restore source-controlled `.idea` configuration files that get overwritten during project import)

If you did not yet setup JDK10 in IntelliJ, Go to `File->Project Structure->Project` and under the `Project SDK` option locate your JAVA_HOME folder, then in `Project language level` beneath select `10 - ...`.

  1. Go to `Build->Build Project`. Everything should build cleanly. You should be able to run tests, run `main` methods in any component, etc.
 
 > 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 `common` project. You can do this via the Gradle tool window in IDEA, or you can do it the command line with `./gradlew :common:generateProto`. Once you've done that, run `Build->Build Project` again and you should have no errors.
