The build operation merges all the rules contained in the rule project to produce the ruleset archive, the standard artifact that a rule engine can read. The ruleset archive contains the IRL code for the rule artifacts that have been selected using a rule project extractor.

To build a rule project:

To rebuild a rule project:

During the build operation, Rule Studio detects problems related to the execution of the ruleset and reports them in the Problems view. The build realizes several level of checking on the rule project elements and compiles the rule artifacts into IRL code.

There are two types of reports:

Some errors come from the way rules are merged into one ruleset file. For instance, if two rule files contain a rule with the same name, there is an error in the resulting ruleset, because there cannot be two rules with the same name in a single ruleset.

When you build your rule project, the errors and warnings appear as entries in the Problems view, and as icons in the Rule Explorer.

Double-click the error item in the Problems view to open the Intellirule Editor or the Java Editor at this position.
