[color=#FF0000:2irwiyqx][junit] jar:file:/E:/apache-ant-1.9.7/lib/ant.jar!/org/apache/tools
/ant/Project.class[/color:2irwiyqx]
Deleted the above mentioned ant.jar and executed "ant clean\build\run" from command prompt
it is saying ANT_HOME not set up correctly.
The above ant.jar points to ANT_HOME environment variable path while other points to Maven repository.
Also the error which is coming in JUnit result file is:-
com.google.common.collect.Multimaps.transformValues(Lcom/google/common/collect/ListMultimap;Lcom/google/common/base/Function;)Lcom/google/common/collect/ListMultimap;
java.lang.NoSuchMethodError: com.google.common.collect.Multimaps.transformValues(Lcom/google/common/collect/ListMultimap;Lcom/google/ccommon/base/Function;)Lcom/google/common/collect/ListMultimap;
