maven - JUnit throws java.lang.NoClassDefFoundError: org/hamcrest/MatcherAssert -

i'm coding tests using junit 4.11 , hamcrest 1.1 following configuration:

<dependency>   <groupid>junit</groupid>   <artifactid>junit</artifactid>   <version>4.11</version>   <scope>test</scope> </dependency>  <dependency>   <groupid>org.hamcrest</groupid>   <artifactid>hamcrest-all</artifactid>   <version>1.1</version>   <scope>test</scope> </dependency> 

and when run them, following exception appears:

java.lang.noclassdeffounderror: org/hamcrest/matcherassert 

in line containing:

assertthat(obj, hasproperty('id', 1l)) 

you should use hamcrest-library instead of hamcrest-all. hamcrest-all not meant used dependency manager because uber-jar contains hamcrest-core , hamcrest-library. following snippet should work.

<dependency>   <groupid>junit</groupid>   <artifactid>junit</artifactid>   <version>4.12</version>   <scope>test</scope> </dependency>  <dependency>   <groupid>org.hamcrest</groupid>   <artifactid>hamcrest-library</artifactid>   <version>1.3</version>   <scope>test</scope> </dependency>
