java - Drools 无法从 InputStream 创建 MavenProject

Question

我有一个 Drools 决策表实现，可以在我的开发机器上运行，但在部署到云中的 VM 时却不行。现在这表明存在部署问题，但对于我来说，我看不出问题出在哪里。

uk.co.example.equi.e​​quiClient 的第 321 行是 kbuilder.buildAll();

这是我得到的错误：

这是代码

    KieServices kieServices = KieServices.Factory.get();

    KieFileSystem kieFileSystem = kieServices.newKieFileSystem();
    Resource resource = kieServices.getResources().newClassPathResource("dtables/applylncc.xlsx");
    // create compiler class instance
    SpreadsheetCompiler sc = new SpreadsheetCompiler();

    kieFileSystem.write(resource);
    KieBuilder kbuilder = kieServices.newKieBuilder(kieFileSystem);

    kbuilder.buildAll();
    KieRepository kieRepository = kieServices.getRepository();
    KieContainer kContainer = kieServices.newKieContainer(kieRepository.getDefaultReleaseId());
    applySession = kContainer.newKieSession();

我也遇到了同样的错误。添加以下依赖项为我解决了这个问题：

<dependency>
    <groupId>org.apache.maven</groupId>
    <artifactId>maven-core</artifactId>
    <version>3.5.2</version>
</dependency>
