MSPM0L1306: CCS Theia 20.4.1 make exits with error code but no message

Part Number: MSPM0L1306

I just imported my (multiple sub-folder) project from CCS 12.5 or so, and when I attempt to build it, make stops after apparently successfully building the last source file but there is no error message.

Can you give me a pointer as to what might be wrong?

Build of configuration 'Debug' for project 'genstart-fw' ****

"C:\\ti\\ccs2041\\ccs\\utils\\bin\\gmake" -k -j 22 all -0

gmake: Target 'all' not remade because of errors.
