【问题描述】：
我的 drools 引擎在远程服务器上运行，可以从我的机器访问。当尝试获取可以在该机器上的工件下看到的 jar 时，我收到以下错误。
Caused by: java.lang.RuntimeException: XSD validation failed against the new schema (cvc-complex-type.3.2.2: Attribute 'sequential' is not allowed to appear in element 'kbase'.) and against the old schema (cvc-elt.1.a: Cannot find the declaration of element 'kmodule'.).

当我在本地机器上按照完全相同的步骤运行 drools docker 时，相同的代码可以正常工作。
public KieContainer kieContainer()
throws IOException {
KieServices ks = KieServices.Factory.get();
KieResources resources = ks.getResources();
String url = ""; // url of the jar created in the drools workbench UI
UrlResource urlResource = (UrlResource) ks.getResources().newUrlResource(url);
urlResource.setUsername("Username");
urlResource.setPassword("Password"`enter code here`);
urlResource.setBasicAuthentication("enabled");
InputStream stream = urlResource.getInputStream();
KieRepository repo = ks.getRepository();
KieModule k = repo.addKieModule(resources.newInputStreamResource(stream));
return ks.newKieContainer(k.getReleaseId());
}
工作台中的 Kmodule：
<?xml version="1.0" encoding="UTF-8"?>
<kmodule xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.drools.org/xsd/kmodule">
<kbase name="ShipmentCheck" default="false" eventProcessingMode="stream" equalsBehavior="identity" packages="splitshipment">
<ksession name="ShipmentCheck" type="stateful" default="true" clockType="realtime"/>
</kbase>
<kbase name="InventoryCheck" default="false" eventProcessingMode="stream" equalsBehavior="identity" packages="inventoryavailability">
<ksession name="InventoryCheck" type="stateful" default="true" clockType="realtime"/>
</kbase>
<kbase name="CapacityCheck" default="false" eventProcessingMode="stream" equalsBehavior="identity" packages="capacity">
<ksession name="CapacityCheck" type="stateful" default="true" clockType="realtime"/>
</kbase>
<kbase name="SafetyStockCheck" default="false" eventProcessingMode="stream" equalsBehavior="identity" packages="safetystock">
<ksession name="SafetyStockCheck" type="stateful" default="true" clockType="realtime"/>
</kbase>
</kmodule>
【问题讨论】：
-
请提供足够的代码，以便其他人更好地理解或重现问题。
-
请包含工作台返回的 kmodule。
