Drools Kie Scanner 7.5.0不起作用

Question

我正在使用Kie-Ci API在本地Maven存储库中扫描最新规则集。Kie-CI升级到版本7.5.0后没有工作。以下是我正在使用的代码。异常说，伪像不存在，但实际上存在于存储库中。使用Kie-CI API创建Kjar Artifact。对此的任何见解都会有所帮助。

代码：

@Async
    @Transactional
    public void scanLatestRuleset(String version){
            log.info("Request received to activate new ruleset version: [ " + version + " ]");
            KieServices kieServices = KieServices.Factory.get();
            ReleaseId releaseId = kieServices.newReleaseId( "com.example", "sample-rules", version );
             //Using Kie Scanner to activate
             this.kieContainer = kieServices.newKieContainer( releaseId );
             KieScanner kScanner = kieServices.newKieScanner( kieContainer );
             kScanner.scanNow();
}

Answer 1

有完全相同的问题。

这似乎是由于JAR xerces:xercesImpl:2.11.0.SP5不在标准存储库中。

正如Mvnrepository在此处所述，需要从JBOSS第三方存储库或其他一些存储库中获取此工件。
