Unix system – Support for custom argument value resolvers for JITL jobs

Current Situation

• With JITL-742 support for custom argument value resolvers was introduced.

• Deployment: Library classes should be packaged in a .jar file and the .jar file should be deployed to the <AGENT_HOME>/lib/user_lib directory

• Problem (Unix systems)
  • Excerpt from agent.log:

    ... info  com.sos.js7.job.resolver.JobArgumentValueResolverCache - [check custom resolvers dir][./user_lib][jar name pattern](?i)^jobapi-register-.*\.jar$
    ... WARN  com.sos.js7.job.resolver.JobArgumentValueResolverCache - [/var/sos-berlin.com/js7/agent/var_4445/./user_lib]java.nio.file.NoSuchFileException: ./user_lib
    

    • The Job API uses the environment variable JS7_AGENT_LIBDIR to locate this folder.
    • This variable is only available when the agent runs on Windows, but not on Unix systems.
    • As a result, the <AGENT_HOME>/lib/user_lib directory is not found on Unix.

Desired Behaviour

• See JS7 - Job Environment Variables
• The Job API should use the JS7_AGENT_HOME variable to locate the user_lib directory, ensuring cross-platform compatibility.

Workaround on Unix
Set the environment variable JS7_AGENT_LIBDIR to point to <AGENT_HOME>/lib in the agent start script.

Test Instructions

• Configure and run any JITL-Job workflow.
• Check the agent.log and look for messages like (these messages are created only once when the first Job API job starts after the Agent starts):

  ... info  com.sos.js7.job.resolver.JobArgumentValueResolverCache - start...
  ... info  com.sos.js7.job.resolver.JobArgumentValueResolverCache - [cached][base64:]com.sos.js7.job.resolver.StandardBase64Resolver
  ... info  com.sos.js7.job.resolver.JobArgumentValueResolverCache - [cached][enc:]com.sos.js7.job.resolver.StandardEncryptionResolver
  ... info  com.sos.js7.job.resolver.JobArgumentValueResolverCache - [check custom resolvers dir][/opt/sos-berlin.com/js7/agent/lib/user_lib][jar name pattern](?i)^jobapi-register-.*\.jar$
  ... info  com.sos.js7.job.resolver.JobArgumentValueResolverCache - end

• The messages should not contain any warnings, and the absolute path to user_lib should be logged instead of a relative path like ./user_lib.
