PowerMock throws NoSuchMethodError (setMockName)

Question

I'm trying to mock a constructor using PowerMockito but every time I run the test I get the following error:

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)

I have the following PowerMock dependencies in my project:

• org.powermock:powermock-module-junit4:1.5.6
• org.powermock:powermock-mockito-release-full:1.5.6

I've traced the dependency tree of my project and fixed conflicts so that mockito-all:1.9.5 gets included in the build.

Answer 1

Make sure powermockito and mockito versions are aligned as in this versions chart - 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

Easy way to find mockito and powermock-mockito version using maven is,

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

Problem could be the conflicting versions of mockito in the application and the one that powermockito uses, conflicting as below in my case where I'm using powermock 1.6.5 which does not support 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

I had

org.mockito mockito-all 1.8.4

added to my pom.xml apart from powermock's dependecies, removing this worked for me.

Answer 3

My problem was due to conflicting versions of javassist in my project's (transitive) dependencies. What I did was search for all dependencies that put old version of javassist in the build, then exclude them. For example:

<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 4

while migrating springboot from 1.5 to 2.0.7 The versions of mockito in springboot and powermock are different so explicitly give mockito dependency

This is compatible while migrating to springboot 2.0.7

testCompile "org.powermock:powermock-api-mockito2:${powermockVersion}"
testCompile group: 'org.mockito', name: 'mockito-core', version: '2.8.9'
testCompile "org.powermock:powermock-module-junit4:1.7.3"
testCompile "org.powermock:powermock-core:1.7.3"

Answer 5

For me, in Eclipse, the fix to this problem was found in Java Build Path. Click on Order and Export tab. Move Web App Libraries to bottom. Note, that when appropriate, this will also allow you to view source of 3rd party libraries when Eclipse tells you that source cannot be found.

In my case it was a conflict dependency. I had fix it after exclude mockito-core artifact:

 <dependency>
        <groupId>com.googlecode.catch-exception</groupId>
        <artifactId>catch-exception</artifactId>
        <exclusions>
            <exclusion>
                <groupId>org.mockito</groupId>
                <artifactId>mockito-core</artifactId>
            </exclusion>
        </exclusions>
        <version>1.0.4</version>
        <scope>test</scope>
    </dependency>

Answer 7

Also, consider removing PowerMock, bytebuddy and objenesis dependencies at all. Keep only the following Mockito dependency.

    <dependency>
        <groupId>org.mockito</groupId>
        <artifactId>mockito-core</artifactId>
        <version>2.7.12</version>
        <scope>test</scope>
    </dependency>

This should fix the error for the most part of the scenarios.
