You need appian-process.jar in your build path for compilation ONLY. DO NOT include it in the final plug-in JAR

So I tried this out and Eclipse is complaining that:

"The method evaluateExpression(String) from the type ProcessDesignService refers to the missing type ExpressionEvaluationException"

What .jar file do I need on my build path to resolve that? Or is this just an error I can safely ignore?

Thanks, evaluateExpression worked great for the purpose.

This is an example that retrieves a constant and checks the constant is of type group. More information at forum.appian.com/.../ProcessDesignService.html

ProcessDesignService pds = ServiceLocator.getProcessDesignService(sc);
TypedValue expressionResult = pds.evaluateExpression("cons!CUSTOM_DESIGNERS_GROUP");

if (expressionResult.getInstanceType() != AppianType.GROUP) {
throw new Exception(
"CUSTOM_DESIGNERS_GROUP is not of the correct data type (Expecting a Group type).");
}

....
