The following covers how to open SignServer in different IDEs.

Apache NetBeans IDE

Open the Maven projects directly in the IDE.

The latest Apache NetBeans IDE (currently 17) is recommended.

Define the top-level project, SignServer, as the main project open in the IDE by right-clicking it and selecting Set as Main Project. This way hitting F6 will be the same as running ant deploy.

The downside is that F11 now maps to Build Main project and it's not convenient to rebuild everything if only working on a small number of modules. To only build the selected project (or the project belonging to the currently open file), the shortcut can be redefined to Build project.

When deploying from within the IDE, specify the environment variable APPSRV_HOME to let the script know where to deploy to.

When working with multiple branches or versions of the projects open in the IDE at the same time, it is useful to configure the IDE to display the version number after each open project:

Click Tools → Options → Java → Maven → Appearance and change Project node name to "${project.artifactId}-${project.version}".

Eclipse IDE

Since each SignServer sub-project is a Maven project, it should be possible to import them into Eclipse like any other Maven project.

IntelliJ IDEA

Since each SignServer sub-project is a Maven project, it should be possible to open the projects directly in IntelliJ IDEA like any other Maven project.
