Getting the message below when trying to run “IFS: Select code generator target version:
The bundled verification helper returned invalid output while checking ifs-dev-buildtasks.jar. The downloaded file was discarded and the existing code generator is unchanged.
Anyone have any idea how to fix it?
Thanks,
That error looks like the extension downloaded a new ifs-dev-buildtasks.jar but its verification step failed, so it kept your existing code generator. Nothing is broken, but you can’t switch versions right now.
Things to try:
Open View > Output in VS Code, select the IFS extension, and check the log. It usually shows the real cause, possibly a Java error, or a checksum mismatch.
Run java -version and confirm it matches what the IFS dev setup requires. A wrong or missing Java can make the helper return invalid output. It needs a java version greater than 11.
Close VS Code, delete any cached ifs-dev-buildtasks.jar (the log shows the path), reopen, and retry.
Update or reinstall the IFS extension, then run Developer: Reload Window.
If it still fails, post the Output panel text here and we can take a closer look
Morning,
I found the problem yesterday, the JDK from my computer was not well configured. So, after update the environment Variables, it worked.
Thanks,
Gianni Neves
