无法加载JDBC驱动程序类 - Spring Batch独立程序

Question

我正在开发一个Spring Batch程序，将其作为命令行应用程序运行（目前通过STS进行测试）。当我通过org.springframework.batch.core.launch.support.CommandLineJobRunner通过Eclipse运行/调试配置运行它时，它无法加载SQL Server JDBC驱动程序。我确定我在类路径上有它，但显然它仍然存在问题。

以下是来自控制台日志的异常跟踪：

我的数据源配置来自spring xml（详细信息已更改为保护无辜者）：

<bean id="legacyDatasource" class="org.springframework.jdbc.datasource.SingleConnectionDataSource">
  <property name="driverClassName" value="com.microsoft.jdbc.sqlserver.SQLServerDriver" />
  <property name="url" value="jdbc:microsoft:sqlserver://server:1433;DatabaseName=database" />
  <property name="username" value="user" />
  <property name="password" value="pw" />
</bean>

现在到类路径的东西......安装在我当地的maven repo中：

在我的pom中：

<dependency>
  <groupId>com.microsoft.sqlserver</groupId>
  <artifactId>sqljdbc41</artifactId>
  <version>4.1</version>
</dependency>

这是我项目的Maven Dependencies：

在我的运行配置中，我尝试将它直接添加到类路径选项卡上的类路径，并通过VM参数。

我很确定这很简单。任何想法为什么驱动程序无法加载？对我而言，值得注意的是，它不是一个没有找到类的错误（虽然它可能在封面下而不是这个堆栈跟踪的一部分）。

有jdbc＆amp; sqlserver在包名中转置。

<bean id="legacyDatasource" class="org.springframework.jdbc.datasource.SingleConnectionDataSource">
  <property name="driverClassName" value="com.microsoft.sqlserver.jdbc.SQLServerDriver" />
  <property name="url" value="jdbc:sqlserver://server:1433;DatabaseName=database" />
  <property name="username" value="user" />
  <property name="password" value="pw" />
</bean>
