Question

我正在将一个项目迁移到Java9中，在我切换到新的Java版本之后，测试开始失败，它看起来像PoerMock正试图访问一些它无法访问的类。

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.973 sec <<< FAILURE! - in com.Test

请，＆＃34;尝试＆＃34;：

<dependency>
  <groupId>org.mockito</groupId>
  <artifactId>mockito-core</artifactId>
  <version>2.18.0</version>
</dependency>
<dependency>
  <groupId>org.powermock</groupId>
  <artifactId>powermock-api-mockito2</artifactId>
  <version>2.0.0-beta.5</version>
</dependency>
<dependency>
  <groupId>org.powermock</groupId>
  <artifactId>powermock-module-junit4</artifactId>
  <version>2.0.0-beta.5</version>
</dependency>

Answer 2

我必须编译一个使用powermock进行测试的第三方jar。为了解决此错误，我必须添加：

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

对于使用powermock测试的类

Answer 3

只是重申sghaier ali提出的非常好的观点。

在被忽略的类中添加*可解决此问题。

所做的更改是：

build.gradle中的以下依赖项：

testImplementation 'org.mockito:mockito-core:3.3.3'
testImplementation 'org.powermock:powermock-api-mockito2:2.0.5'
testImplementation 'org.powermock:powermock-module-junit4:2.0.5'

通过以下方式注释特定的类：

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

Answer 4

正如@ smac89所述，我要做的就是忽略有问题的软件包。

通过用@PowerMockIgnore("jdk.internal.reflect.*")注释我的测试班

我的Maven依赖项是：

    <dependency>
        <groupId>org.powermock</groupId>
        <artifactId>powermock-module-junit4</artifactId>
        <version>1.7.4</version>
        <scope>test</scope>
      </dependency>
    <dependency>
      <groupId>org.powermock</groupId>
      <artifactId>powermock-api-mockito</artifactId>
      <version>1.7.4</version>
      <scope>test</scope>
    </dependency>

Java版本：

java -version
openjdk version "11.0.1" 2018-10-16
OpenJDK Runtime Environment 18.9 (build 11.0.1+13)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.1+13, mixed mode)

尝试使用Oracle JDK 1.8运行它
