MockClassLoader 无法访问 jdk/internal/reflect superclass jdk.internal.reflect.MagicAccessorImpl

java maven powermock powermockito

我正在将一个项目迁移到Java9中，测试在我切换到新的Java版本后开始失败，似乎PowerMock正在尝试访问一些它无法访问的类。

答案 1

我对使用powermock的第三方jar进行了测试依赖。为了解决这个错误，我不得不添加：

@PowerMockIgnore("jdk.internal.reflect.*")

到测试的类powermock

答案 2

这是一个（目前）@powermock的开放问题，但对于Java 9，这应该有效：

<dependency>
  <groupId>org.mockito</groupId>
  <artifactId>mockito-core</artifactId>
  <version>2.18.0</version> <!-- or higher, correspondning to powermock-version -->
</dependency>
<dependency>
  <groupId>org.powermock</groupId>
  <artifactId>powermock-api-mockito2</artifactId>
  <version>2.0.0-beta.5</version> <!-- or higher -->
</dependency>
<dependency>
  <groupId>org.powermock</groupId>
  <artifactId>powermock-module-junit4</artifactId>
  <version>2.0.0-beta.5</version> <!-- or higher -->
</dependency>

在Java 11中，Mosheer-Ahmad设法运行了他的测试，包括：

上述依赖关系，
对和的额外依赖org.javassist javassist 3.24.1-GA test

这个（测试基）类/注释：

@RunWith(PowerMockRunner.class)
@PowerMockIgnore({"javax.management.", "com.sun.org.apache.xerces.", 
  "javax.xml.", "org.xml.", "org.w3c.dom.",
  "com.sun.org.apache.xalan.", "javax.activation.*"})
public class PowerMockitoBaseRunner {

}
