I'm new in the Android world. I opened studio Android 2.2 and, after creating a new project, I get this error message:
Failed to sync Gradle project '...'
Error:Unable to load class 'org.slf4j.LoggerFactory'. Possible causes for this unexpected error include:
In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.
- Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.) Re-download dependencies and sync project (requires network)
- The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem. Stop Gradle build processes (requires restart)
- Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.
How can I fix the problem? Thanks
Go to File
-> Settings
-> Expand Build, Execution, Deployment
-> Select Build Tools
-> Gradle
-> Under Project Level Settings
Select Use default gradle wrapper
. Try Gradle build again and this worked for me.
