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.

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.
