记一次maven报错解决：Failed to read artifact descriptor for com.aliyun.openservices:aliyun-openservices:jar:2.0.0-OTS
今天从svn更新代码后，代码一直报错，pom.xml文件也显示有错误，看了代码后发现是同事用了aliyun的一些包，他开发的时候，jar还可以下载，过了几天到我这对应jar从maven中下载不下来，还连他现在也下载不了了，我Maven install后也是报错：

pom.xml文件配置如下：
<dependency>
<groupId>com.aliyun.openservices</groupId>
<artifactId>aliyun-openservices</artifactId>
<version>2.0.0-OTS</version>
</dependency>重复操作了几次Maven clean和install，对应的jar一直下载不下来。总是报如上错误，后来叫旁边同事看了下，他怀疑是不是版本问题，后来换一个版本重新下载，发现项目不报错了，jar下载下来了，可能是仓库里的2.0.0-OTS版本被删除了或有问题下架了吧。所以这个问题告诉我们，jar包下载不下来时，换个版本也是一种解决方案。
改完后的pom.xml配置：
<dependency>
<groupId>com.aliyun.openservices</groupId>
<artifactId>aliyun-openservices</artifactId>
<version>OTS-2.0.4</version>
</dependency>
