PowerMock抛出NoSuchMethodError(setMockName)

Question

我正在尝试使用模拟构造函数,PowerMockito但每次运行测试时都会出现以下错误:

java.lang.NoSuchMethodError: org.mockito.internal.creation.MockSettingsImpl.setMockName(Lorg/mockito/mock/MockName;)Lorg/mockito/internal/creation/settings/CreationSettings;
at org.powermock.api.mockito.internal.mockcreation.MockCreator.createMethodInvocationControl(MockCreator.java:107)
at org.powermock.api.mockito.internal.mockcreation.MockCreator.mock(MockCreator.java:60)
at org.powermock.api.mockito.internal.expectation.DefaultConstructorExpectationSetup.createNewSubstituteMock(DefaultConstructorExpectationSetup.java:105)
at org.powermock.api.mockito.internal.expectation.DefaultConstructorExpectationSetup.withAnyArguments(DefaultConstructorExpectationSetup.java:71)

我的项目中有以下PowerMock依赖项:

• org.powermock:powermock模块-junit4:1.5.6
• org.powermock:powermock-的Mockito释放全:1.5.6

我已经跟踪了我的项目的依赖树并修复了冲突,以便mockito-all:1.9.5包含在构建中.

确保powermockito和mockito版本一致,如此版本图表中所示 - MockitoUsage#supported-versions,

Mockito                     | PowerMock
------------------------------------------------------------------------------
2.0.0-beta - 2.0.42-beta    |   1.6.5+
------------------------------------------------------------------------------
1.10.19                     |   1.6.4
1.10.8 - 1.10.x             |   1.6.2+
1.9.5-rc1 - 1.9.5           |   1.5.0 - 1.5.6
1.9.0-rc1 & 1.9.0           |   1.4.10 - 1.4.12
1.8.5                       |   1.3.9 - 1.4.9
1.8.4                       |   1.3.7 & 1.3.8
1.8.3                       |   1.3.6
1.8.1 & 1.8.2               |   1.3.5
1.8                         |   1.3
1.7                         |   1.2.5

使用maven 查找mockito和powermock-mockito版本的简便方法是,

mvn dependency:tree | grep mockito
[INFO] |  \- org.mockito:mockito-core:jar:1.8.5:compile
[INFO] +- org.mockito:mockito-all:jar:1.8.5:compile
[INFO] +- org.powermock:powermock-api-mockito:jar:1.4.9:compile

问题可能是mockito应用程序中的冲突版本和powermockito使用的冲突版本,在我使用的情况下如下所示冲突,我powermock 1.6.5不支持mockito 1.8.5

mvn clean dependency:tree | grep mockito
[INFO] +- org.mockito:mockito-all:jar:1.8.5:compile

[INFO] \- org.powermock:powermock-api-mockito:jar:1.6.5:compile
[INFO]    +- org.mockito:mockito-core:jar:1.10.19:compile
[INFO]    \- org.powermock:powermock-api-mockito-common:jar:1.6.5:compile

Answer 2

我的问题是由于我的项目(传递)依赖项中的javassist版本冲突.我所做的是搜索在构建中放置旧版本javassist的所有依赖项,然后排除它们.例如:

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-entitymanager</artifactId>
    <version>3.5.1-Final</version>
    <scope>provided</scope>
    <exclusions>
        <exclusion>
            <groupId>javassist</groupId>
            <artifactId>javassist</artifactId>
        </exclusion>
    </exclusions>
</dependency>

Answer 3

我有

org.mockito mockito-all 1.8.4

添加到我的pom.xml除了powermock的dependecies,删除这对我有用.
