通过Maven shade插件包含SQL Server JDBC驱动程序的Uber / fat jar

标签： maven

我正在尝试通过Maven dependency构建一个包含SQL Server JDBC驱动程序的示例jar。连接到db和查询的类在IDE（IntelliJ）中正确编译和执行。

当我从IntelliJ执行'mvn clean install'或'install'时，构建的jar只包含我编写的db类，但不包含SQL Server JDBC jar（我想应该采用分解格式）。

有趣的部分是如果我包含另一个依赖项，例如：scala并在sql server之前提供它，uber jar包含所需的依赖项，并且sql代码可以从目标jar执行得很好。我认为由于某种原因，在构建jar时没有拾取sql server jdbc jar。下面的pom工作得很好，并提供了所需的超级罐：

将以下范围从测试更改为编译

 <dependency>
  <groupId>com.microsoft.sqlserver</groupId>
  <artifactId>mssql-jdbc</artifactId>
  <version>6.3.4.jre8-preview</version>
  <scope>test</scope>
</dependency>

在下方使用可以提供帮助

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>2.4.3</version>
        <executions>
            <execution>
                <phase>package</phase>
                <goals>
                    <goal>shade</goal>
                </goals>
                <configuration>
                    <shadedArtifactAttached>true</shadedArtifactAttached>
                    <shadedClassifierName>all</shadedClassifierName>

                </configuration>
            </execution>
        </executions>
    </plugin>
