How to fix git after upgrade to El Capitan?

When the new OS version is ready to install a lot of developers are asking a question: Is everything will work after upgrade right after the release date? But not OS X users.

Unfortunately after upgrade to El Capitan 10.11 (from Yosemite) my command line git stopped work. I got such message:

xcrun: error: invalid active developer path (/Library/Developer/CommandLineTools), missing xcrun at: /Library/Developer/CommandLineTools/usr/bin/xcrun
 !    Git appears to be installed incorrectly
 !    Ensure that `git --version` outputs the version correctly.

Use @Deprecated Java class without compilation warning

The first rule of using deprecated classes is to do not use deprecated classes. If you have to use such class then double check how to avoid such situation and find newer implementation of deprecated class (most of the time the new alternative solution is provided). But if you really forced to use deprecated class (e.g. 3rd-party library) then during class compilation (compileJava and compileTestJava Gradle tasks) you will get below warning:

Note: <path_to_your_class_where_deprecated_class_is_used>.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

I will show you few solutions how to disable this warning.
