Execution failed for task ':library:proguardRelease'

Issue

I just updated sdk and android studio i have this problem:

    Error:Execution failed for task ':library:proguardRelease'.
> java.lang.NullPointerException (no error message)

How can i solve this?

Can i go home?

Solution

First, try to use clean.

Second, if that doesn't help, get more info about the failure. You can use the following parameters for your build command:

• -i will print the logs with INFO level
• -d will print the logs with DEBUG level
• -s will print the exception stack trace

e.g., running ./gradlew assemble -d -s should give you a lot of information that can help locate the issue.
