How to import RapidMiner JARs in Eclipse? - java

I want to create a RapidMiner classifier on Java that classifies a user based on his/her touch input. I have searched for days now, I have RapidMiner Studio and have downloaded the rapidMiner-studio from github - but I don't know which one should I include on my library/build path.
Do I just include all of them? Any help would be greatly appreciated.

I found the answer to my question, so far I found out that you can run a process ( a .rmp) file you created from RapidMiner in Eclipse, and the JAR files i added are located at C:\Program Files\RapidMiner\RapidMiner Studio\lib
Here's my code:
package rapid_process;
import com.rapidminer.Process;
import com.rapidminer.RapidMiner;
import com.rapidminer.operator.Operator;
import com.rapidminer.operator.OperatorException;
//import com.rapidminer.operator.io.ExcelExampleSource;
import com.rapidminer.tools.XMLException;
import java.io.File;
import java.io.IOException;
import java.lang.Object;
public class process {
public static void main(String[] args) throws IOException, XMLException, OperatorException {
/*// Path to process-definition
final String processPath = "C:/Users/Evie/.RapidMiner/repositories/Local Repository/processes/Compare ROCs.rmp";
// Init RapidMiner
RapidMiner.setExecutionMode(ExecutionMode.COMMAND_LINE);
RapidMiner.init();
// Load process
final com.rapidminer.Process process = new com.rapidminer.Process(new File(processPath));
process.run();*/
try {
RapidMiner.setExecutionMode(RapidMiner.ExecutionMode.COMMAND_LINE);
RapidMiner.init();
Process process = new Process(new File("C:/Users/YourUser/.RapidMiner/repositories/Local Repository/processes/Compare ROCs.rmp"));
process.run();
} catch (IOException | XMLException | OperatorException ex) {
ex.printStackTrace();
}
}
}

Problem: cannot resolve constructor CSVPrinter

I'm trying to generate and load from CSV filea and problem with CSVPrinter occured. The statement is the following:
Cannot resolve constructor 'CSVPrinter(java.io.BufferedWriter,org.apache.commons.csv.CSVFormat)"
import org.apache.commons.csv.CSVFormat;
import org.apache.commons.csv.CSVParser;
import org.apache.commons.csv.CSVPrinter;
import org.apache.commons.csv.CSVRecord;
import java.io.BufferedWriter;
import java.io.*;
import java.net.URL;
import java.nio.file.Files;
import java.nio.file.Paths;
try (BufferedWriter writer = Files.newBufferedWriter(Paths.get(file.getAbsolutePath()));
CSVPrinter csvPrinter = new CSVPrinter(writer, CSVFormat.DEFAULT
.withHeader("title", "description", "priority"))
) {
for (int i = 0; i < serializer.toDO.size(); i++){
csvPrinter.printRecord(serializer.toDO.get(i).getTitle(),
serializer.toDO.get(i).getDescription().replace("\n"," "),
serializer.toDO.get(i).getPriority(),
serializer.toDO.get(i).getLocalDate(),
"toDo");
}
Assuming you are using the apache variant, your code worked for me.
I think you need to add some of the details that you assure us you have done. My guess is that you have the wrong library in your project/classpath.
In what environment are you running your code (within the IDE or standalone from the command prompt)?
How did you incorporate the library (download JAR directly from Apache or automatically via a service - e.g. maven)?
Here is my version of the source code:
package csvwriter;
import java.io.BufferedWriter;
import java.io.File;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.logging.Level;
import java.util.logging.Logger;
import org.apache.commons.csv.CSVPrinter;
import org.apache.commons.csv.CSVFormat;
public class Main {
/**
* #param args the command line arguments
*/
public static void main(String[] args) {
Main m = new Main();
m.go(args);
}
public void go(String [] args) {
File file = new File (args[0]);
try (BufferedWriter writer = Files.newBufferedWriter(Paths.get(file.getAbsolutePath()));
CSVPrinter csvPrinter = new CSVPrinter(writer, CSVFormat.DEFAULT
.withHeader("title", "description", "priority"))
) {
System.out.println("Done.");
// for (int i = 0; i < serializer.toDO.size(); i++){
// csvPrinter.printRecord(serializer.toDO.get(i).getTitle(),
// serializer.toDO.get(i).getDescription().replace("\n"," "),
// serializer.toDO.get(i).getPriority(),
// serializer.toDO.get(i).getLocalDate(),
// "toDo");
// }
} catch (IOException ex) {
Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
}
}
}
Here are my libraries:
I downloaded the library from the apache download center
When I run, I get the following as the output:
run:
Done.

How to create a file from an action event for an IntelliJ plugin?

I'm creating a PhpStorm plugin with IntelliJ IDEA Community Edition and I would like to know how to create a file on disk from a PSIFile or VirtualFile.
Here my code: (The context is an action from NewGroup)
I've tried to use the PsiDirectory.copyFileFrom method to create the file but I have an exception com.intellij.util.IncorrectOperationException: Cannot copy non-physical file: PHP file
package fr.florent.idea.zendgenerator.action.NewGroup;
import com.intellij.openapi.actionSystem.AnActionEvent;
import com.intellij.openapi.actionSystem.LangDataKeys;
import com.intellij.openapi.fileEditor.impl.LoadTextUtil;
import com.intellij.openapi.vfs.VfsUtil;
import com.intellij.openapi.vfs.VirtualFile;
import com.intellij.psi.PsiDirectory;
import com.intellij.psi.PsiFile;
import com.intellij.psi.PsiFileFactory;
import com.intellij.util.ResourceUtil;
import com.jetbrains.php.lang.PhpFileType;
import fr.florent.idea.zendgenerator.action.AbstractDumbAwareAction;
import icons.PhpIcons;
import org.jetbrains.annotations.NotNull;
import java.net.URL;
public class CreateQueryAction extends AbstractDumbAwareAction {
public CreateQueryAction() {
super("Query", "Create query", PhpIcons.Php_icon);
}
#Override
public void actionPerformed(#NotNull AnActionEvent e) {
URL url = ResourceUtil.getResource(getClass(), "templates", "query.php"); // it contains an empty PHP class
VirtualFile virtualFile = VfsUtil.findFileByURL(url);
PsiFile file = PsiFileFactory.getInstance(e.getProject()).createFileFromText(
virtualFile.getPath(),
PhpFileType.INSTANCE,
LoadTextUtil.loadText(virtualFile)
);
PsiDirectory directory = LangDataKeys.IDE_VIEW.getData(e.getDataContext()).getOrChooseDirectory();
directory.copyFileFrom("query.php", file);
System.out.println("Create query");
}
}
I would like to have the file created in the project folder from the context of my action.
It will be great if someone can explain the process of creating a file in a IntelliJ plugin. I think the docs is really light.
In my case I would like to have the process to edit the query.php file, rename the class name, add method, properties, doc block and save it to the disk but I don't understand the PSI element.
You might want to ask this also on JB forum, there's a similar question: https://intellij-support.jetbrains.com/hc/en-us/community/posts/360001787320-Create-VirtualFile-or-PsiFile-from-content
The answer is:
final PsiFileFactory factory = PsiFileFactory.getInstance(project);
final PsiFile file = factory.createFileFromText(language, text);

Include an exe-file into jar and run it

I tried to to include an exe-file into a jar-Application and to run it. The idea is to extract it temporary at first and then to run the temp-exe-file. How to do that? That is what I have tried. There is my code. It occurs the exception java.io.FileNotFoundException because of the source file "ffmpeg.exe". I verified, but the file is included and the directory is correct.
package extractffmpeg;
import java.io.File;
import java.io.IOException;
import java.net.URISyntaxException;
import java.net.URL;
import javafx.application.Application;
import javafx.application.Platform;
import javafx.stage.Stage;
import org.apache.commons.io.FileUtils;
public class ExtractFFmpeg extends Application {
public void start(Stage primaryStage) throws IOException, URISyntaxException {
extractExe();
System.out.println("extract successfull");
Platform.exit();
}
public static void main(String[] args) {
launch(args);
}
public void extractExe() throws URISyntaxException, IOException{
final String resourcesPath = "ffmpeg/ffmpeg.exe";
URL url = ExtractFFmpeg.class.getResource(resourcesPath);
File source = new File(url.toString());
System.out.println("shows url of ffmpeg: " + url.getPath());
System.out.println("shows file of ffmpeg: " + source);
File destination = new File("C:/Users/FNI2Abt/Desktop/ffmpeg.exe");
FileUtils.copyFile(source, destination);
}
}
The idea is to create a self-extracting archive. The archive shall contain both JAR and EXE. The JAR file shall contain a class which would call Process.exec(...) on the adjacent EXE. Starting there, you can follow this tutorial:
How do I make a self extract and running installer

How to setup zxing library on Windows 8 machine?

I have images of codes that I want to decode. How can I use zxing so that I specify the image location and get the decoded text back, and in case the decoding fails (it will for some images, that's the project), it gives me an error.
How can I setup zxing on my Windows machine? I downloaded the jar file, but I don't know where to start. I understand I'll have to create a code to read the image and supply it to the library reader method, but a guide how to do that would be very helpful.
I was able to do it. Downloaded the source and added the following code. Bit rustic, but gets the work done.
import com.google.zxing.NotFoundException;
import com.google.zxing.ChecksumException;
import com.google.zxing.FormatException;
import com.google.zxing.BarcodeFormat;
import com.google.zxing.DecodeHintType;
import com.google.zxing.Reader;
import com.google.zxing.BinaryBitmap;
import com.google.zxing.Result;
import com.google.zxing.LuminanceSource;
import com.google.zxing.client.j2se.BufferedImageLuminanceSource;
import com.google.zxing.common.HybridBinarizer;
import java.awt.image.BufferedImage;
import javax.imageio.ImageIO;
import java.io.File;
import java.io.IOException;
import java.util.*;
import com.google.zxing.qrcode.QRCodeReader;
class qr
{
public static void main(String args[])
{
Reader xReader = new QRCodeReader();
BufferedImage dest = null;
try
{
dest = ImageIO.read(new File(args[0]));
}
catch(IOException e)
{
System.out.println("Cannot load input image");
}
LuminanceSource source = new BufferedImageLuminanceSource(dest);
BinaryBitmap bitmap = new BinaryBitmap(new HybridBinarizer(source));
Vector<BarcodeFormat> barcodeFormats = new Vector<BarcodeFormat>();
barcodeFormats.add(BarcodeFormat.QR_CODE);
HashMap<DecodeHintType, Object> decodeHints = new HashMap<DecodeHintType, Object>(3);
decodeHints.put(DecodeHintType.POSSIBLE_FORMATS, barcodeFormats);
decodeHints.put(DecodeHintType.TRY_HARDER, Boolean.TRUE);
Result result = null;
try
{
result = xReader.decode(bitmap, decodeHints);
System.out.println("Code Decoded");
String text = result.getText();
System.out.println(text);
}
catch(NotFoundException e)
{
System.out.println("Decoding Failed");
}
catch(ChecksumException e)
{
System.out.println("Checksum error");
}
catch(FormatException e)
{
System.out.println("Wrong format");
}
}
}
The project includes a class called CommandLineRunner which you can simply call from the command line. You can also look at its source to see how it works and reuse it.
There is nothing to install or set up. It's a library. Typically you don't download the jar but declare it as a dependency in your Maven-based project.
If you just want to send an image to decode, use http://zxing.org/w/decode.jspx

streamscraper java lib eclipse

I have this code:
import java.net.URI;
import java.util.List;
import net.moraleboost.streamscraper.Stream;
import net.moraleboost.streamscraper.Scraper;
import net.moraleboost.streamscraper.scraper.IceCastScraper;
public class Harvester
{
public static void main(String[] args) throws Exception
{
Scraper scraper = new IceCastScraper();
List<Stream> streams = scraper.scrape(new URI("http://host:port/"));
for (Stream stream: streams) {
System.out.println("Song Title: " + stream.getCurrentSong());
System.out.println("URI: " + stream.getUri());
}
}
}
Where do I download JAR for import net.moraleboost.streamscraper.* to work? I can find source code for it but I gives me load of errors, can someone just provide me .jar so I could include in java build path library?
You can clone the repository at https://code.google.com/p/streamscraper/
You can also download the code from here: https://code.google.com/p/streamscraper/source/browse/
