When using the Managed Dependencies feature, a vendorlib-sbom.json file is generated in the vendorlib folder. We generate this document with the help of the CycloneDx Gradle plugin. This is downloaded on your local environment from the Gradle Plugin Repository.
On an air-gapped/internet-restricted setup, downloading the plugin will fail if there is no access to the plugin repository. To mitigate this issue, we have created a custom repository containing the CycloneDx Gradle plugin.
You need to configure Studio Pro to use this repository. The steps to configure can be found in the Custom Repository section of Mendix Docs.
After configuring Studio Pro, you'll be able to build and run your application successfully and the vendorlib-sbom.json file will also be generated.
If you are finding trouble configuring Studio Pro or you are faced with different errors, please contact Mendix Support
