maven仓库添加jar架包

推荐几个好的 Maven 常用仓库网址：
http://mvnrepository.com/
http://search.maven.org/
http://repository.sonatype.org/content/groups/public/
http://people.apache.org/repo/m2-snapshot-repository/
http://people.apache.org/repo/m2-incubating-repository/

以 ojdbc14.jar为例，下载后再pom.xml中查看这个 jar 包的 groupId，artifactId，version信息，
手动安装的时候这些信息不要改，否则 Maven 项目移植的话，jar 包下载就会失败。顺便把这信息帖下面，方便对照：

		<dependency>
			<groupId>com.oracle</groupId>
			<artifactId>ojdbc14</artifactId>
			<version>10.2.0</version>
		</dependency>

Maven 安装 JAR 包的命令是：

mvn install:install-file -Dfile=jar包的位置 -DgroupId=上面的groupId -DartifactId=上面的artifactId -Dversion=上面的version -Dpackaging=jar

[root@p ~]# mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc14 -Dversion=10.2.0 -Dpackaging=jar -Dfile=/root/ojdbc14.jar
