Minimum version of Gradle?

Does your project require a minimum version of Gradle to be successfully imported into a project?

We run our builds using gradle. I created a test project to play around and get to know the library before trying to integrate with our project(s). My test project works find.

However, I created a small test class to run in our product and when I try to test it out, I get NoClassDefFoundError on the line TrainTestSplitter<Label> dataSplitter = new TrainTestSplitter<>(csvDatasource);.

I’m convinced that the issue is with importing dependencies. Our projects use Gradle v5.6.2 and I don’t know if/when they plan to upgrade.

In contrast, my working test project is building with Gradle v.7.1

System details

• Tribuo version : 4.1.0
• Java version (if appropriate) openJDK 11.0.7
• OS/Architecture (if appropriate) MacOS 14.1.1

Thanks. That is the plan. For now I’m just trying to hack together a POC so tribuo-all is the easiest way to guarantee I get the parts I need without having to deep dive into the libraries.

Your team has been a great help. I’ve asked a few questions now and your responsiveness and helpfulness has been on point.

Excellent, I’m glad you’ve got it sorted out. If you’re looking at integrating Tribuo into a larger project I recommend you pare back the dependencies by only using the bits of Tribuo you need, rather than depending on tribuo-all. tribuo-all is for getting up and running quickly for prototyping, but it pulls in bulky native dependencies like ONNX Runtime and TensorFlow which might not be necessary for your use case.
