auth maven工件构建错误

Question

我正在尝试用maven构建一个android应用程序，我想使用Spring框架。我已将必要的依赖项添加到我的pom.xml中如下：

<dependencies>
<dependency>
    <groupId>org.springframework.android</groupId>
    <artifactId>spring-android-rest-template</artifactId>
    <version>1.0.1.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.android</groupId>
    <artifactId>spring-android-auth</artifactId>
    <version>1.0.1.RELEASE</version>
</dependency>
<dependency>
    <groupId>org.springframework.android</groupId>
    <artifactId>spring-android-core</artifactId>
    <version>1.0.1.RELEASE</version>
</dependency>

​

使用maven构建失败的maven-eclipse插件2.9。我还尝试用命令行maven 3.0.5构建我的项目，这两种方法都告诉我：

[INFO] UNEXPECTED TOP-LEVEL EXCEPTION:
[INFO] java.lang.IllegalArgumentException: already added: Lorg/springframework/core/ErrorCoded;

如果我从我的pom.xml中移除spring auth依赖项，该项目将成功构建。但是，如果我只将此保留为依赖项，并删除其他所有内容，则错误将保持不变。

所以我想建造春季android-auth人工制品有一个问题。我是不是做错了什么，还是有谁在经历同样的问题？如果可以修好的话，我该怎么解决呢？

以下是我对该项目的实际整个pom.xml：

我猜您对spring auth依赖关系有问题，这种依赖关系与:spring核心库有冲突。

我建议你把org.sprframework. suggest core排除在其中：

<dependency>
  <groupId>org.springframework.android</groupId>
  <artifactId>spring-android-auth</artifactId>
  <version>${spring-android-version}</version>
  <exclusions>

    <!-- Exclude in favor of Spring Android Core -->
    <exclusion>
      <artifactId>spring-core</artifactId>
      <groupId>org.springframework</groupId>
    </exclusion>

  </exclusions>
</dependency>
