Drools Kie Scanner 6.3.0最终抛出ProvisionException（未找到RepositorySystem）

Question

我刚开始使用Drools，并试图将其与我的Spark流媒体工作相结合。我使用Drools6.3.0.final和kie-ci，这样我就可以从spark工作中远程拉出我的kJar，如果有新的版本，就可以使用kie扫描器进行更新。然而，我遇到了以下异常：

016-04-27 10:22:32,360 WARN  [streaming-job-executor-0] Sisu (Logs.java:warn(394)) - Error injecting: org.apache.maven.execution.DefaultMavenExecutionRequestPopulator

我已经在我的settings.xml中设置了远程存储库，在这里我正确地运行spark，因为当它正确地创建KieContainer时，它会拉出最新的jar。只有当我出于某种原因包括KieScanner时，它才会失败。

KieServices ks = KieServices.Factory.get();
ReleaseId releaseId = ks.newReleaseId("test", "test", "LATEST");
KieContainer kieContainer = ks.newKieContainer(releaseId);
KieSession kSession = kieContainer.newKieSession();

KieScanner kScanner = ks.newKieScanner(kieContainer);
kScanner.scanNow();
kSession.fireAllRules();
kSession.dispose();

（java.lang.nosuchmethoderror：com.google.inject.binder.BindListener）

有人知道为什么或者我怎么能解决这个问题吗？

我也遇到过类似的问题，为Flink生成一个uber罐子。这是因为我的maven shade配置不完整，来自不同JAR的Meta-inf/**配置文件被覆盖。通过在Maven shade配置中添加以下变形金刚来解决这个问题：

<transformer implementation="org.apache.maven.plugins.shade.resource.ComponentsXmlResourceTransformer"/>
<transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"/>
<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
    <resource>META-INF/sisu/javax.inject.Named</resource>
</transformer>
