Java Security Exception

lizzy1 — Sat, 16 Nov 2024 05:29:03 GMT

I have a very simple job consisting of a tRestClient leading to tExtractJSONFields to tBigQueryOutput.

This results in the following error

Exception in component tBigQueryOutput_1_tBQBE (job_name)
java.lang.SecurityException: class "com.google.common.base.MoreObjects"'s signer information does not match signer information of other classes in the same package

How can I solve this?

I have successfully used the tBigQueryOutput in other jobs, and if I replace the BigQuery output with a CSV output, the job runs fine.

Hello,

This error indicatesyou have two or more classes in the same package with different signature data. Usually that means the classes come from different JARs, one of which is signed and the other is unsigned.

Could you please indicate on which talend build version you got this issue?

Best regards

Sabrina

I don't know. I was able to work around it by replacing the tRestClient with a tRest.
