Cause

After running the git clone https://github.com/cloudfoundry/java-buildpack, the resulting files may not contain the proper permissions.

A common reason for this *umask* value was 0027.

Resolution

In some cases, the environment "umask "settings are set to a more secure value such as "0027".

Ensure that "umask" value is set to "0022" to avoid this in the future. Otherwise, ensure the permissions are set as follows:

Good buildpack permissions

drwxr-xr-x 5 user1 staff 170 Mar 2 12:19 .
drwxr-xr-x 25 user1 staff 850 Mar 2 12:19 ..
-rwxr-xr-x 1 user1 staff 954 Mar 2 12:19 compile
-rwxr-xr-x 1 user1 staff 1099 Mar 2 12:19 detect
-rwxr-xr-x 1 user1 staff 976 Mar 2 12:19 release


Bad buildpack permissions

drwxr-x---@ 5 user1 staff 170 Feb 24 12:43 .
drwx------@ 7 user1 staff 238 Mar 2 15:02 ..
-rwxr-x---@ 1 user1 staff 954 Feb 24 12:43 compile
-rwxr-x---@ 1 user1 staff 1099 Feb 24 12:43 detect
-rwxr-x---@ 1 user1 staff 976 Feb 24 12:43 release 

The default installed JRE may not be Oracle. For example, if the user has OpenJDK installed, then the build pack could return this error when deploying the app. Refer to How to verify Java configuration, to determine what version of java is installed.
