      There is a Spring Boot application (based on business-application-{model,kjar,service} generated from start.jbpm.org) which contains Kie Server and also contains business-application-kjar by configuration (*1) with properties (*2). After adding a dependency to commons-beanutils (1.9.4.redhat-00002) in business-application-kjar/pom.xml like (*3) for using functions of it, an error "Could not read pom in jar" like (*e) occurs while the Spring Boot application is launching.

      (*e)

      [main] ERROR o.a.m.i.InJarArtifactResolver - Could not read pom in jar jar:file:/path/to/reproducer_business-application_1a/business-application-service/target/business-application-service-1.0-SNAPSHOT.jar!/BOOT-INF/classes/KIE-INF/lib/commons-beanutils-1.9.4.redhat-00002.jar!/META-INF/maven/commons-beanutils/commons-beanutils/pom.xml

      When the error occurs at start-up, the Kie Server in the Spring Boot application is actually trying to look for some artifacts in local maven repository (~/.m2/repository). So, we can avoid the error (*e) by installing those artifacts in the local maven repository in advance like (*4), but originally the Spring Boot application should be able to start independently without installing artifacts in the local maven repository.

      (*1) There is the following description in business-application-service/pom.xml.

      <plugin>

  <artifactId>kie-maven-plugin</artifactId>
  <version>${version.org.kie}</version>

      </artifactItem>
    </artifactItems>
  </configuration>
</plugin>

      (*2) There are two lines in business-application-service/src/main/resources/application-dev.properties.

      kieserver.classPathContainer=true
kieserver.autoScanDeployments=true

      (*3) There is a dependency to commons-beanutils-1.9.4.redhat-00002.jar in business-application-kjar/pom.xml.

      <dependency>
  <groupId>commons-beanutils</groupId>
  <artifactId>commons-beanutils</artifactId>
  <version>1.9.4.redhat-00002</version>
</dependency>
