Mallet library - encoders.ser and Manifest.MF not found (cleartk-ml-mallet-1.2.2.jar)

[Sunil Mandhan]

I am trying to use Mallet CRF for NER. I am getting following errors. I am stuck here, any quick response will be appreciated.

java.io.FileNotFoundException: d:\models\attribext\MANIFEST.MF (The system cannot find the file specified)
    at java.io.FileInputStream.open(Native Method)
    at java.io.FileInputStream.<init>(FileInputStream.java:120)
    at org.cleartk.classifier.jar.JarClassifierBuilder.fromTrainingDirectory(JarClassifierBuilder.java:88)
    at org.cleartk.classifier.jar.JarClassifierBuilder.trainAndPackage(JarClassifierBuilder.java:126)
    at org.cleartk.classifier.jar.Train.main(Train.java:59)

My understanding is MANIFEST.MF and encoders.ser should be created automatically. But why they are not being created here.
I am using cleartk-ml-mallet-1.2.2.jar along with cTAKES 3.1.2-SNAPSHOT

I got it working by adding the following
  if (this.isTraining())
        this.collectionProcessComplete();

after the training data write operation and before Train.main method call. By calling this method, encoders.ser and Manifest.MF are automatically generated.

Sorry about the long delayed response, but yes, if you are running the
pipeline, you must call collectionProcessComplete() for the various
files to be written.
