我有一个非常简单的项目，我正在试验 BPM（Quarkus、Kogito、jBPM 和 Drools），但它无法在 Java 11 上构建。这是 github 存储库：https ://github.com/JoaoCamposFrom94/bpmdemo/tree /2808d87428ddb91c43c0b2554a5808ca4299293e

该项目有几个 REST 端点，它们将表单保存在哈希图中。我打算通过使用 drools 来验证端点 POST /demo/form/{id} 上的某些字段，并通过启动一个在端点 POST /demo/form 上执行任意 java 代码的简单进程来使用 jBPM 来试验。

通过运行，mvn compile quarkus:dev我在一些生成的代码中遇到错误。

import org.kie.kogito.Config;

@javax.inject.Singleton()
public class Application implements org.kie.kogito.Application {

    @org.eclipse.microprofile.config.inject.ConfigProperty(name = "kogito.service.url", defaultValue = "")
    java.lang.String kogitoService;

    @javax.inject.Inject()
    org.kie.kogito.Config config;

    public Config config() {
        return config;
    }
}
...
(class changed for brevity)

这在https://groups.google.com/forum/#!topic/kogito-development/Xkkon4tLHdo得到了回答。

我的 pom.xml 指定了一个 kogito 构建插件和一个 quarkus 构建插件。两者都导致冲突，我只是删除了 kogito 构建插件。
