java - Quarkus ClassNotFoundException 本地依赖

Question

我正在尝试将项目迁移到 Quarkus。该项目依赖于本地 .jar 文件。使用 Quarkus 运行应用程序结果为 java.lang.NoClassDefFoundError/java.lang.ClassNotFoundException对于驻留在所述 jar 中的类。

我使用 gradle 作为构建工具，并使用以下方法将本地 jar 文件添加为依赖项:

implementation fileTree(dir: 'libs', include: ['*.jar'])

假设库包含一些类 Foo使用静态方法init() ，那么以下代码将导致错误:

// From the local jar
import org.somepackage.Foo;

@Startup
@Singleton
public class Main {

  @PostConstruct
  public void initLocalLibrary() {
    Foo.init();
  }

}

确切的输出是

在没有 Quarkus 的情况下运行应用程序效果很好。

请尝试更换

实现 fileTree(dir: 'libs', include: ['*.jar'])

与

api fileTree(dir: 'libs', include: ['*.jar'])
