Using compiled versions of Routines with the Test Run feature in Talend Data Mapper

Subscription
You cannot test maps using the Test Run feature available in the Mapping perspective if a function that was defined in the Integration perspective under Code > Routines is called in one of the maps. Using the Test Run feature on such a map will result in errors. This issue occurs because Studio routines are not on the classpath during development. Test Run , in the Mapping perspective, has no access to the compiled versions of these routines.
Resolution

A workaround is to import a compiled version of these routines into your project.

To do so, do the following.

  1. In a command window, go to the <talend_studio_path>/workspace/.Java folder.
  2. Type mvn package .

    This creates a routines.A.B.C.jar file in <talend_studio_path>/workspace/.Java/target which contains is a compiled version of the routines.

  3. In the Studio , open the Navigator view and find your project.
  4. Right click the Project, and then click Properties > Mapping .
  5. Click Add JAR and add <talend_studio_path]/workspace/.Java/target/routines-A.B.C.jar to your project.

After this, you will be able to use the Test Run feature as required.
