Graph Database plugin fails to load in GoLand 2025.2 due to missing JsonFileType class #98
Description
When using the Graph Database plugin (v0.8.0) in GoLand 2025.2, the plugin fails to initialize with the following error:
Caused by: java.lang.NoClassDefFoundError: com/intellij/json/JsonFileType
It seems the plugin relies on the com.intellij.json.JsonFileType class, which is not available in GoLand by default. This prevents the Console ToolWindow from loading and renders the plugin unusable.
Steps to reproduce:
- Install GoLand 2025.2
- Install Graph Database plugin v0.8.0
- Restart IDE
- Observe the error and failure of the Graph Console ToolWindow to initialize
Expected behavior:
The plugin should load successfully or provide a clear warning if a required dependency (like JSON support) is missing.
Additional information:
- GoLand 2025.2
- Graph Database plugin v0.8.0
