This seems to be a bug in the KieServices and the SPring Boot uber jar. There is a work around posted here:
<a href="https://groups.google.com/forum/#!topic/drools-usage/odQjmBess5A" rel="nofollow noreferrer">https://groups.google.com/forum/#!topic/drools-usage/odQjmBess5A</a>

Basically, configure the Spring Boot Maven Plugin to unpack the kie jar(s).

<pre><code> &lt;plugin&gt;
 &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
 &lt;artifactId&gt;spring-boot-maven-plugin&lt;/artifactId&gt;
 &lt;configuration&gt;
 &lt;requiresUnpack&gt;
 &lt;dependency&gt;
 &lt;groupId&gt;com.sample&lt;/groupId&gt;
 &lt;artifactId&gt;kproject1&lt;/artifactId&gt;
 &lt;/dependency&gt;

 &lt;dependency&gt;
 &lt;groupId&gt;com.sample&lt;/groupId&gt;
 &lt;artifactId&gt;kproject2&lt;/artifactId&gt;
 &lt;/dependency&gt;
 &lt;/requiresUnpack&gt;

 &lt;/configuration&gt;
 &lt;executions&gt;
 &lt;execution&gt;
 &lt;phase&gt;package&lt;/phase&gt;
 &lt;goals&gt;
 &lt;goal&gt;repackage&lt;/goal&gt;
 &lt;/goals&gt;
 &lt;/execution&gt;
 &lt;/executions&gt;
 &lt;/plugin&gt;
</code></pre>

Make sure you have the following dependencies 

<pre><code>implementation group: 'org.kie', name: 'kie-api', version: '7.16.0.Final'
implementation group: 'org.drools', name: 'drools-core', version: '7.16.0.Final'

implementation group: 'org.kie', name: 'kie-spring', version: '7.16.0.Final'
</code></pre>

and remove <code>spring-boot-devtools</code> dependency if you have one. 

(This worked for me.)

blocks|key|816272|text|当使用spring+devtools时，这是因为您的事实通常使用“重新启动Classloader”加载，而Drools类则使用“because”加载。因此，事实对象在执行规则时不匹配。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|816273|通过在我的spring应用程序中创建一个包含以下内容的文件src/main/resources/META-INF/spring-devtools.properties，我也为Drools类使用了“重新启动Classloader”来解决这个问题：|816274|restart.include.dools=/(drools%7Ckie)\-.*\.jar|code-block|syntax|javascript|816275|相关弹簧文档|offset|length|816276|entityMap|0|LINK|mutability|MUTABLE|url|https://docs.spring.io/spring-boot/docs/current/reference/html/using-boot-devtools.html#using-boot-devtools-customizing-classload^0|0|0|0|0|6|0|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|V|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|W|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|X|8|@]|9|@$K|Y|L|Z|1|10]]|A|$]]|$1|M|3|-4|5|6|7|11|8|@]|9|@]|A|$]]]|N|$O|$5|P|Q|R|A|$S|T]]]]

When using spring-boot-devtools, this is because your facts usually gets loaded using "Restart Classloader" and your Drools classes using "Base Classloader". Therefore the fact objects does not match when your rules are executed. 

I resolved this problem by using "Restart Classloader" for Drools classes too, by creating a file src/main/resources/META-INF/spring-devtools.properties in my spring-boot-application with following content: 

<pre><code>restart.include.dools=/(drools|kie)\-.*\.jar
</code></pre>

blocks|key|1630810|text|这是Drools中的错误，并且已经在JIRA：sscc=t中解决了。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1630811|entityMap|0|LINK|mutability|MUTABLE|url|https://issues.redhat.com/browse/DROOLS-2311?_sscc=t^0|N|6|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

That was the bug in Drools and has been solved under this JIRA :
<a href="https://issues.redhat.com/browse/DROOLS-2311?_sscc=t" rel="nofollow noreferrer">https://issues.redhat.com/browse/DROOLS-2311?_sscc=t</a>

I am using the Drools 7.5.0-final in the spring Boot project.

I am working on a multi-module Gradle project. 
Rules and kmodule.xml is present in the sub-module project. This module is packaged as a Jar inside a fat spring boot Jar file.

<pre><code> &lt;?xml version="1.0" encoding="UTF-8"?&gt;
&lt;kmodule xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
 xmlns="http://jboss.org/kie/6.0.0/kmodule"&gt;
&lt;!-- &lt;configuration&gt;
 &lt;property key="drools.propertySpecific" value="ALLOWED"/&gt;
&lt;/configuration&gt; --&gt;

&lt;kbase name="rules.employee.tax" packages="uk.gov.hmrc.itmp.service.application.rules.employee.tax" &gt; 
&lt;ksession name="rules.employee.tax.session" type="stateful" /&gt;
&lt;ksession name="rules.employee.tax.statelesssession" type="stateless" /&gt;
&lt;/kbase&gt; 
&lt;/kmodule&gt;
</code></pre>

I am building the container from the classpath.

<pre><code>KieContainer kContainer = kieService.newKieClasspathContainer();
</code></pre>

on server start-up (java -jar) it loads the Kmodule.xml and prints all the kbase and sessionName.

But when I fire rules it returns <code>zero rules fired</code>.

It works fine when I run as spring boot app from Eclipse.
Please help.
