Talend Studio allows you to create custom routine jars and set up custom routine jar dependencies on Jobs and Joblets if you have installed the R2021-03 Studio monthly update or a later one provided by Talend.
The custom routine jar allows you to package multiple user routines with their dependencies into a single archive. By setting up custom routine jar dependencies on Jobs and Joblets, the code dependencies for Jobs and Joblets become more explicit and this can help reduce dependency conflicts.
