将Eclipse Birt 4.5.0 源码引入Eclipse 一、下载源码在Birt官网下载版本 4.5.0,解压后如图所示链接：http://www.eclipse.org/birt/ 依次点击链接下载：Download Birt 4.5.0 → Full 4.5.0 Download Page → BIRT Source Code 全部是JAR格式的文件，与之前的版本完全不同啊二、进入Eclipse进行配置阅读详情

用birt想连接数据库，把数据展示出来用birt做报表，版本是4.3.2 连接mysql.如果报表没有涉及连接数据库，很正常，但是如果是有需要连接数据库的，一直报错，按照网上很多种做法都没用，在apache-tomcat-7.0.54\webapps\birt\WEB-INF\lib 下面放驱动包没用，还有说在WEB-INF/platform/plugins/org.eclipse.birt.report.data.oda.jdbc_4.3.2.v20140211-1400/drivers下面放驱动包，可是4.3.2的版本根本就没有这个目录。报错如下：
