Android Studio - Error:Unable to load class 'o

Question

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:

• 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.

In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

How can I fix the problem? Thanks

Answer 1

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.

Answer 2

I solve this by following steps

1. download the newest version of gradle in this site: http://download.csdn.net/download/fallingwind/9604349

2. replace folder "disk-label://android-studio/gradle" with the download file(unarchive first).

3. restart AS

4. if it doesn't work, you can change the environment path of gradle.exe
