我正在使用 Kie-CI api 扫描本地 maven 存储库中的最新规则集。升级到 7.5.0 版后，Kie-CI 无法正常工作。下面是我正在使用的代码。异常说工件不存在，但实际上工件存在于存储库中。KJAR 工件是使用 Kie-CI api 创建的。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();
}

日志：

有完全相同的问题。

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

正如 MvnRepository在这里所说，这个工件需要从JBoss 3rd Party 存储库或其他一些存储库中获取。
