maven的jar包冲突问题解决方案

报错信息:

An attempt was made to call the method com.google.common.collect.FluentIterable.append(Ljava/lang/Iterable;)Lcom/google/common/collect/FluentIterable; but it does not exist. Its class, com.google.common.collect.FluentIterable, is available from the following locations:
    jar:file:/C:/Users/XXX/.m2/repository/com/google/guava/guava/16.0.1/guava-16.0.1.jar!/com/google/common/collect/FluentIterable.class
It was loaded from the following location:
    file:/C:/Users/XXX/.m2/repository/com/google/guava/guava/16.0.1/guava-16.0.1.jar

这个原因是导入jar包的时候，jar包兼容性问题
