我创建了一个 Java 应用程序(试点)来运行水壶转换。这很简单,我只有 main 方法,它获取一个 .ktr 文件并执行它。
public static void main( String[] args )
{
try {
KettleEnvironment.init();
TransMeta transMeta = new TransMeta("C:\\user\\car.ktr");
Trans trans = new Trans(transMeta); //create new transformation object
trans.execute(null);
trans.waitUntilFinished();
} catch (KettleException e) {
e.printStackTrace();
}
}
问题是当我运行它时,我得到一个异常。

它用 maven 创建了这个应用程序,我有这些依赖项。
