Pentaho数据集成SQL连接

我正在使用Pentaho数据集成，我试图通过MySQL连接到我的数据库，但当我这样做时，我得到了这个错误.....
Error connecting to database [devdb2] : org.pentaho.di.core.exception.KettleDatabaseException:

我错过了一个库或一个类吗？

原来我遗漏了一个名为mysql-connector-java-5.1.2.jar的类，我将它添加到这个文件夹(C:\Program Files\pentaho\design-tools\data-integration\lib) )，它可以使用MySQL连接，然后我的数据和表格就会出现。

您需要下载mysql-connector-java-5.1.46.tar.gz，而不是最新版本。在mysql-connector-java-8.xx.yy版本中，没有包含Pentaho使用的驱动程序类。

除了这里的其他答案之外，下面是你如何在Ubuntu (14.04)上做到这一点：
sudo apt-get install libmysql-java
这会将mysql-connector-java-5.x.x.jar下载到/usr/share/java/，我相信它还会自动创建一个名为mysql-connector-java.jar的符号链接。
然后，在/your/path/to/data-integration/lib/中创建符号链接
ln -s /usr/share/java/mysql-connector-java.jar /your/path/to/data-integration/lib/mysql-connector-java.jar
