Any help will be appreciated thanks :)

[greenrobot-team]

Look at the output of the Gradle task :buildEnvironment (for plugins) and :app:dependencies (for "regular" dependencies) and check if there are conflicting dependency versions. You might have to exclude or force a specific version of com.google.code.findbugs:jsr305.

Indeed ,there are a conflict in CheckForSigned class , i exluded com.google.code.findbugs:jsr305 and the compile works fine .thanks a lot
