My ant build worked perfectly until I upgraded from "Runtime Environment 18.9 (build 11+28) 2018-09-25" to "build 11.0.14+9-post-Debian-1deb10u1"
Now I see lots of
[javac] /home/user/workspace/project/source/net/sf/cglib/transform/DumpFieldsTask.java:1: error: cannot access net.sf.cglib.transform
[javac] package net.sf.cglib.transform;
[javac] ZIP file can't be opened as a file system because an entry has a '.' or '..' element in its name
What do I have to do ?
