问题

因Oracle授权问题，Maven3不提供Oracle JDBC 对应的驱动jar包。 因此 ，如果在在Maven项目中使用Oracle JDBC driver,必须手动添加到本地仓库。

解决办法

1、 确认本机安装了Maven

在命令窗口通过mvn -v查看版本

E:\libs\oracle>mvn -v
Apache Maven 3.5.0 (ff8f5e7444045639af65f6095c62210b5713f426; 2017-04-03T15:39:06-04:00)
Maven home: E:\libs\apache-maven-3.5.0-bin\apache-maven-3.5.0\bin\..
Java version: 1.7.0_51, vendor: Oracle Corporation
Java home: E:\Program Files\Java\jdk1.7.0_51\jre
Default locale: zh_CN, platform encoding: GBK
OS name: "windows 8", version: "6.2", arch: "amd64", family: "windows"

2、下载对应版本的数据库驱动

官方下载jar：

http://www.oracle.com/technetwork/database/features/jdbc/index-091264.html

查看自己的数据库版本，下载对应版本的jar包

Oracle Database 11g Release 2 (11.2.0.4), (11.2.0.3), (11.2.0.2.0), (11.2.0.1.0) drivers 对应的 jar包为 ojdbc6.jar

通过本地安装目录查找

如果你在本机装了oracle，在 {ORACLE_HOME}\jdbc\lib下查找

oracle的驱动包说明

    classes12.jar - for Java 1.2 and 1.3

    ojdbc14.jar - for Java 1.4 and 1.5

    ojdbc5.jar - for Java 1.5

    ojdbc6.jar - for Java 1.6

因此最高的版本 目前是 ojdbc6 .

3、安装驱动到本地仓库

进入到对应的目录，执行 mvn install 命令
