org.gradle.tooling.model.UnsupportedMethodException: Unsupported method: HierarchicalEclipseProject.getIdentifier().
The version of Gradle you connect to does not support that method.
To resolve the problem you can change/upgrade the target version of Gradle you connect to.
Alternatively, you can ignore this exception and read other information from the model.
