After the download is complete, extract the files to your hard disk. Use of the Eclipse plug-in is not required. Rule files are just textual input or spreadsheets as the case may be and the IDE also known as the Rule Workbench is just a convenience.
People have integrated the rule engine in many ways, there is no "one size fits all". Alternatively, you can download the binary distribution, and include the relevant jars in your projects classpath. In many cases, people will simply want to include all the dependencies at runtime, and this is fine. It allows you to have the most flexibility. However, some may prefer to have their "runtime" stripped down to the bare minimum, as they will be deploying rules in binary form - this is also possible.
The core runtime engine can be quite compact, and only requires a few kilobytes across 3 jar files. It also helps clearly show what is intended as a user api and what is just an engine api. This is the only runtime dependency if you are pre-compiling rules and deploying via Package or RuleBase objects.
This is often a runtime dependency of your application, but it need not be if you are pre-compiling your rules. This depends on drools-core. Note that due to the nature of the JSR specification, not all features are easily exposed via this interface. This supports both excel and CSV input formats. There are quite a few other dependencies which the above components require, most of which are for the drools-compiler, drools-jsr94 or drools-decisiontables module.
Some key ones to note are "POI" which provides the spreadsheet parsing ability, and "antlr" which provides the parsing for the rule language itself.
Set the system property "drools. For up to date info on dependencies in a release, consult the released poms, which can be found on the maven repository. The jars are also available in the central maven repository and also in the JBoss maven repository. This is similar for Gradle, Ivy and Buildr. To identify the latest version, check the maven repository. If you're still using ANT without Ivy , copy all the jars from the download zip's binaries directory and manually verify that your classpath doesn't contain duplicate jars.
The "runtime" requirements mentioned here are if you are deploying rules as their binary form either as KnowledgePackage objects, or KnowledgeBase objects etc. This is an optional feature that allows you to keep your runtime very light. You may use drools-compiler to produce rule packages "out of process", and then deploy them to a runtime system. This runtime system only requires drools-core.
This is an optional deployment pattern, and many people do not need to "trim" their application this much, but it is an ideal option for certain environments.
The rule workbench for Eclipse requires that you have Eclipse 3. You can install it either by downloading the plug-in or, or using the update site. Another option is to use the JBoss IDE, which comes with all the plug-in requirements pre packaged, as well as a choice of other tools separate to rules. Location is:. Press next, and agree to install the plug-in an Eclipse restart may be required.
Once this is completed, then you can continue on installing the rules plug-in. To install from the zip file, download and unzip the file. Inside the zip you will see a plug-in directory, and the plug-in jar itself. You place the plug-in jar into your Eclipse applications plug-in directory, and restart Eclipse. Unzip the downloaded file in your main eclipse folder do not just copy the file there, extract it so that the feature and plugin jars end up in the features and plugin directory of eclipse and re start Eclipse.
Guvnor 5. Older community releases can be found in the release archive. Red Hat customers can download the product platforms from the product downloads site. Business Central Workbench Showcase. KIE Execution Server. For more info about the Drools Docker images see this blog post.
The latest releases, including 7. Final are available in the Maven Central Repository. To use them, first configure the JBoss Maven repository. We stopped to release Eclipse tools synchronously with Drools, thus the recent version of Drools and of latest released Eclipse tools updatesite may differ. Click here to go to the Drools and jBPM update site latest released version 7. Alternatively, you can download the latest released version of Drools and jBPM tools zip 7. Want to talk to the experts?
