Question

使用Maven 3.5.4运行Java测试时遇到以下问题。和OpenJdk 11。

下面是使用的版本：

org.powermock:powermock-module-junit4:jar:1.6.5
org.powermock:powermock-api-mockito-common:jar:1.6.5
org.powermock:powermock-core:jar:1.6.5
org.javassist:javassist:jar:3.23.1-GA

这是执行堆栈跟踪：

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 0.541 sec <<< FAILURE! - in <Class_Name(hidden)>
    initializationError(<Class_Name(hidden)>)  Time elapsed: 0.018 sec  <<< ERROR!
    java.lang.IllegalStateException: Failed to transform class with name <Class_Name(hidden)>. Reason: null

Answer 1

升级到最新版本的Hibernate（5.3.7.Final）时遇到了这个问题。似乎Hibernate对Javassist有依赖关系，该依赖关系已更新为3.23.1-GA。

Javassist和Powermock的最新版本存在一个问题，应在Javassist 3.24.0中修复，请参见：https://github.com/powermock/powermock/issues/924

作为解决方法，直到新的Javaassist版本发布，将其添加到我的pom中解决了我的问题：

<dependency>
    <groupId>org.javassist</groupId>
    <artifactId>javassist</artifactId>
    <version>3.22.0-GA</version>
    <scope>test</scope>
</dependency>
