我的ivy.xml配置文件该修改的都修改了还是报错呢

<dependency org="org.apache.gora" name="gora-sql" rev="0.1.1-incubating" conf="*->default" />

    <!-- Uncomment this to use MySQL as database with SQL as Gora store. -->

    <dependency org="mysql" name="mysql-connector-java" rev="5.5.8" conf="*->default"/>

    <!-- Uncomment this to use HBase as Gora backend. -->
    <!-- 
    <dependency org="org.apache.gora" name="gora-hbase" rev="0.3" conf="*->default" />
    -->
    <!-- Uncomment this to use Accumulo as Gora backend. -->
    <!-- 
    <dependency org="org.apache.gora" name="gora-accumulo" rev="0.3" conf="*->default" />
    -->
    <!-- Uncomment this to use Cassandra as Gora backend. -->

    <dependency org="org.apache.gora" name="gora-cassandra" rev="0.2.1" conf="*->default"-- />

复制代码

注销的还不够，只留下这行即可，其余都去掉

  <dependency org="org.apache.gora" name="gora-cassandra" rev="0.2.1" conf="*->default"-- />

应该不是这个问题：配置你能说具体点吗？

    <dependency org="org.restlet.jse" name="org.restlet" rev="2.0.5" conf="*->default" />
    <dependency org="org.restlet.jse" name="org.restlet.ext.jackson" rev="2.0.5" 
      conf="*->default" />

没有接触你的环境，你可以自己试验，我的建议是，在你的这个配置里

<dependency org="org.apache.gora" name="gora-sql" rev="0.1.1-incubating" conf="*->default" />

    <!-- Uncomment this to use MySQL as database with SQL as Gora store. -->

    <dependency org="mysql" name="mysql-connector-java" rev="5.5.8" conf="*->default"/>

    <!-- Uncomment this to use HBase as Gora backend. -->
    <!--
    <dependency org="org.apache.gora" name="gora-hbase" rev="0.3" conf="*->default" />
    -->
    <!-- Uncomment this to use Accumulo as Gora backend. -->
    <!--
    <dependency org="org.apache.gora" name="gora-accumulo" rev="0.3" conf="*->default" />
    -->
    <!-- Uncomment this to use Cassandra as Gora backend. -->

    <dependency org="org.apache.gora" name="gora-cassandra" rev="0.2.1" conf="*->default"-- />

只留下这个配置：

  <dependency org="org.apache.gora" name="gora-cassandra" rev="0.2.1" conf="*->default"-- />
复制代码

其余都去掉。

如果你有更好的方案或则方法，你可以按照你自己的思路，这里只是给你一些提示和建议。
