Build issue, MojoExecutionHelper issue

pthomas — Fri, 31 Oct 2025 12:47:44 GMT

I have a project that was fine. Until...

I was entering a 300+ column json file in Metadata, I clicked the Next button and the project froze. I left for a couple hours thinking it would catch up and that the file was too large. Finally, with Talend not responding, I closed it via the terminal. Now no matter what I run, however basic the project won't build. I'm getting the error below.

The Talend server is behind firewalls with no internet connectivity and prior to crashing was working fine.

Any suggestions would be appreciated.

Hello,

The error: has been compiled by a more recent version of the Java Runtime (class file version 61.0), this version of the Java Runtime only recognizes class file versions up to 52.0
means the java version used to "run" Talend Studio is Java 8 (52.0) and the class is Java 17 (61.0)

Could you check you have 2 lines like the one below at the beginning of the file Talend-Studio-win-x86_64.ini

-vm
c:\talend\zulu17\bin

Kind regards
Denis

I have a -vmargs on the 2nd line.

Further below that I do have a line for Java version.

-Dosgi.requiredJavaVersion=17

That's the way the beginning of the file looks. I'm on Linux not Window and I am comparing a working server to the broken one but the files match each other and what you posted.
