Good Morning Rolf,
please double check your dependencies: I think it's FOP instead of FOP-
CORE.
For me, the following dependencies work with Java21 and I get nice PDFs
out:
// PDF Output
implementation ('org.apache.xmlgraphics:fop:+') {
exclude group: 'xalan', module: 'xalan'
}
implementation ('org.apache.xmlgraphics:batik-codec:+') {
exclude group: 'xalan', module: 'xalan'
}
Viel Glueck!
