找不到ID Kettle

Question

我试图在Java中集成Kettle并执行一个转换。这些软件包被正确下载。但是，当我试图以Java应用程序的形式运行转换时，我会收到以下异常：

Unable to find plugin with ID 'Kettle'.  If this is a test, make sure kettle-core tests jar is a dependency.  If this is live make sure a kettle-password-encoder-plugins.xml exits in the classpath

我正在运行Java 8，希望有一个简单的解决方案

Answer 1

经过几天的调查，我终于找到了一个解决办法

我添加了一个新的Source文件夹，其中包含‘kettle-password-编码器-plugins.xml’文件。

UPDATE：您可以轻松地删除资源上的文件，因此它包含在类路径中。

即：

<password-encoder-plugins>
  <password-encoder-plugin id="Kettle">
    <description>Kettle Password Encoder</description>
    <classname>org.pentaho.support.encryption.KettleTwoWayPasswordEncoder</classname>
  </password-encoder-plugin>
</password-encoder-plugins>

而且看起来挺好的。

在项目中为这个文件创建一个文件夹，然后在IDE (在我的例子中是Eclipse)中，您应该可以看到在中创建的文件夹。然后右击->生成路径->用作源文件夹
