Gradle project report "cannot resolve class" for Bundle-Activator

[chi-bin]

Describe the bug I am developing with this plugin and gradle(compile and package) in IDEA.My project fileTree like this

xxxxproject:
     - META-INF/MANIFEST
     - src/main/java/....
     - build.gradle
     - plugins.xml

when I try to resolve my project , Bundle-Activator said class not found

gradle makes my project have subproject named "main" in IDEA , and source code belong to it ，I guess that is reason. how to solve it ? thanks

At present, the v1.x version does not support compilation systems other than IntellIJ, so this error is inevitable😓

It is planned to completely reconstruct the project in the v2.x version to support systems such as Gradle.
