maven - Eclipse: The type org.hamcrest.core.CombinableMatcher$CombinableBothMatcher cannot be resolved. It is indirectly referenced from required .class files -

i working on unit testing spring mvc controller using testng , mockito. i've included hamcrest library in maven dependencies shown below. missing here? error shows when use following 2 methods:

org.hamcrest.matchers.hassize; org.hamcrest.matchers.is; 

the following dependencies:

<dependency>     <groupid>org.testng</groupid>     <artifactid>testng</artifactid>     <version>6.9.4</version>     <scope>test</scope> </dependency> <dependency>     <groupid>org.mockito</groupid>     <artifactid>mockito-core</artifactid>     <version>1.10.8</version>     <scope>test</scope> </dependency> <dependency>     <groupid>org.hamcrest</groupid>     <artifactid>hamcrest-library</artifactid>     <version>1.3</version>     <scope>test</scope> </dependency> 

update 1:

the problem has been resolved changing hamcrest-library hamcrest-all.

    <dependency>         <groupid>org.hamcrest</groupid>         <artifactid>hamcrest-all</artifactid>         <version>1.3</version>         <scope>test</scope>     </dependency> 

update 2:

as per suggested tunaki, better solution exclude transitive dependency hamcrest-core mockito library. final dependencies should follows:

<dependency>     <groupid>org.mockito</groupid>     <artifactid>mockito-core</artifactid>     <version>1.10.8</version>     <scope>test</scope>     <exclusions>         <exclusion>             <groupid>org.hamcrest</groupid>             <artifactid>hamcrest-core</artifactid>         </exclusion>     </exclusions> </dependency> <dependency>     <groupid>org.hamcrest</groupid>     <artifactid>hamcrest-library</artifactid>     <version>1.3</version>     <scope>test</scope> </dependency> 

there dependency conflict in pom:

• mockito-core 1.10.8 depends on hamcrest-core 1.1.
• hamcrest-library 1.3 depends on hamcrest-core 1.3.

maven resolves conflict selecting version 1.1 (it declared first , have equal path).

you getting error because hamcrest-library 1.3 references combinablematcher class that did not exist in version 1.1 does exist in version 1.3.

if depend on hamcrest 1.3 specific features, need exclude hamcrest-core transitive dependency mockito-core (and hope hamcrest 1.3 backwards compatible 1.1). otherwise, remove hamcrest-library , depend on hamcrest 1.1.
