Getting java.lang.NoSuchMethodError when running new v4.1.2 install

[markgif]

I get this weird error when running a freshly-installed DITA OT 4.1.2:

bin\dita -i C:\dita-api-manual\sample.ditamap -f pdf2 --temp=temp -v
Searching for integrator.xml ...
init:
dita2pdf2.init:
init-properties:
[init-project] Initializing project
Error: java.lang.NoSuchMethodError: 'net.sf.saxon.Configuration net.sf.saxon.Configuration.newConfiguration()'

I'm using Windows 11, using Java 17, openjdk version 17.0.8.1.

My DITA-OT\lib folder contains these files:

I fixed this myself. I had forgotten I had installed 2 very old and rather non-standard plugins to the clean DITA OT 4.1.2. I started from scratch again without those 2 plugins, and it ran. Sorry!

But it was an interesting error, wasn't it?

Maybe one of those plugins had a Saxon library inside it as well?
Initially I suspected your problem might be related to specifying in the system classpath extra JAR libraries like this situation: #4342 (comment)

Hi Radu, I was too quick to mark this as answered, it was still failing in Win11 command prompt (without my old plugins), even though it worked slightly better in Git Bash.

BUT:
Your tip about the classpath reminded me that I had set the classpath on this Win11 machine to an old Saxon version for some command line Saxon work, and when I cleared that classpath, DITA OT 4.1.2 worked just fine! It's fixed! Basic classpath user error.

Thanks,
Mark
