Google App添加联系人错误? [英] Google App add contact error?

问题描述

在我的GAE应用程序中，有以下一行:

In my GAE app there is the following line :

ContactsService myService=new ContactsService("app-name");

它编译正常，但是运行时会导致以下错误:

It compiled fine, but when run, it cause the following error :

Exception in thread "main" java.lang.NoSuchMethodError: com.google.common.collect.Iterators.forArray([Ljava/lang/Object;)Lcom/google/common/collect/UnmodifiableIterator;
    at com.google.common.collect.ImmutableSet$ArrayImmutableSet.iterator(ImmutableSet.java:415)
    at com.google.common.collect.ImmutableSet$ArrayImmutableSet.iterator(ImmutableSet.java:392)

我已经包含了guava-r09.jar，所以它具有"ImmutableSet"，如果我不包含guava-r09.jar，它将说:

I've included guava-r09.jar, so it has the "ImmutableSet", if I don't included guava-r09.jar, it will say :

线程"main"中的异常java.lang.NoClassDefFoundError:com/google/common/collect/ImmutableSet

Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/collect/ImmutableSet

我该怎么办?

推荐答案

我发现了原因:不需要包括google-collect-*.jar(错误源).

I found out why : don't need to include google-collect-*.jar, source of error.
