Have updated grunt from 1.0.4 to 1.3.0 , after upgrade if i run grunt , receiving the following error.

Verifying property mkdir.doc exists in config...OK
File: [no files]
Options: mode=null, create=["./build/documentation"]
Options: mode=null, create=["./build/documentation"]
Creating "./build/documentation"...ERROR
>> Error: Unable to create directory "./build/documentation" (Error code: ERR_INVALID_ARG_VALUE).
Warning: Mkdir operation failed. Use --force to continue.

Aborted due to warnings.

Gone through this link https://github.com/SAP/cloud-mta-build-tool/issues/857 but couldn't get the solution. Please share your ideas.

Answer 1

Found the solution:

Its because of grunt-mkdir npm.

After adding mode of directory creation its worked

mkdir: { 
abc: {
            options: {
                mode: 0777,
                create: ['./build/abc']
            }
        }
}
