ObjectBoxGeneratorCommand doesn't recognise entity files

[kemkriszt]

Is there an existing issue?

• [ x] I have searched existing issues

Build info

• ObjectBox version: 4.4.1
• OS: running on macOS 15.7, project targets iOS 17
• Device/chipset: M1 Pro

Steps to reproduce

1. Reintegrate Cocoapods from existing project, remove all files and build step for auto generation
2. Add objectbox SPM
3. Ensured I don't have any Folders, only Groups
4. Run ObjectBoxGeneratorCommand plugin

Expected behavior

Source files are correctly autogenerated

Actual behavior

All enttiy data is removed from the EntityInfo-* file.
For example, cModel looks like this:

fileprivate func cModel() throws -> OpaquePointer {
    let modelBuilder = try ObjectBox.ModelBuilder()
    // Previously had ~15 x try SomeEntity.buildEntity(modelBuilder: modelBuilder)
    modelBuilder.lastEntity(id: 27, uid: 5950384143574972928)
    modelBuilder.lastIndex(id: 36, uid: 8353492716365687552)
    modelBuilder.lastRelation(id: 8, uid: 5131698544966963456)
    return modelBuilder.finish()
}

🟩 The plugin execution finished.
！ Add the generated source file in 'generated/EntityInfo-Target.generated.swift' to the project and version control
！ Add the generated model file in 'model-Target.json' to version control, this is important for ObjectBox model generation

Thanks for reporting.

Not sure if related, but Sourcery, the code generator the plugin uses, appears to have issues with accessing the file system:

I hope this is a helpful starting point for you to get this fixed.

You can also try to add the --verbose argument when running the plugin to get some additional log output.

It seems that the --verbose option causes Xcode to hang forever. This is the only output I get:

working directory:
   /Users/x/Documents/iOS/project-folder
tool mapping:
   objectbox-generator: /Users/x/Library/Developer/Xcode/DerivedData/xxx-xxx/SourcePackages/artifacts/objectbox-swift-spm/ObjectBoxGenerator/Contents/MacOS/Sourcery [arm64-apple-macosx]
tool paths:
   /Applications/Xcode-26.0.1.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
   /Applications/Xcode-26.0.1.app/Contents/Developer/usr/bin
   /bin
   /sbin
   /usr/bin
   /usr/sbin

(Note that I did update my Xcode to 26.0.1 since I opened the issue but it doesn't seem to make a difference)

I've checked the cache directory but it doesn't seem to exist, probably that's why the plugin can't access it
