Importing descriptor with included import

Im trying load descriptors from external source.
When using generated files without imports it works without problem but when proto have imports then while building FileDescriptor I gets DescriptorValidationException:
Failed to parse descriptor ./descriptors/test.dsc
com.google.protobuf.Descriptors$DescriptorValidationException: AccessRequest.date_from: ".google.protobuf.Timestamp" is not defined.
Proto file which i use to get *.dsc file:
syntax = "proto3";
import "google/protobuf/timestamp.proto";
message AccessRequest {
int64 cabinet_id = 1;
google.protobuf.Timestamp date_from = 2;
google.protobuf.Timestamp date_to = 3;
}
Command which I use to get *.dsc:
protoc --include_imports --proto_path=src/main/proto/ --descriptor_set_out=descriptors/test.dsc src/main/proto/test.proto
My code to load *.dsc files:
try (final InputStream stream = Files.newInputStream(path)) {
final FileDescriptorSet fds = FileDescriptorSet.parseFrom(stream);
final TypeRegistry.Builder builder = TypeRegistry.newBuilder();
for (final FileDescriptorProto fdp : fds.getFileList()) {
final FileDescriptor fd = FileDescriptor.buildFrom(fdp, new FileDescriptor[]{});
builder.add(fd.getMessageTypes());
globalBuilder.add(fd.getMessageTypes());
}
return new Queue(base, builder.build());
}

FileDescriptor.buildFrom(fdp, new FileDescriptor[]{}) is the key point.
You should build the dependency proto(import) recursively, and take the result to replace the second parameter.
Give you my code for reference
private FileDescriptor buildFileDescriptor(FileDescriptorProto currentFileProto,
Map<String, FileDescriptorProto> fileProtoCache) {
List<FileDescriptor> dependencyFileDescriptorList = new ArrayList<>();
currentFileProto.getDependencyList().forEach(dependencyStr -> {
FileDescriptorProto dependencyFileProto = fileProtoCache.get(dependencyStr);
FileDescriptor dependencyFileDescriptor = buildFileDescriptor(dependencyFileProto, fileProtoCache);
dependencyFileDescriptorList.add(dependencyFileDescriptor);
});
try {
return FileDescriptor.buildFrom(currentFileProto, dependencyFileDescriptorList.toArray(new FileDescriptor[0]));
} catch (DescriptorValidationException e) {
throw new IllegalStateException("FileDescriptor build fail!", e);
}
}

I know it's late but incase someone is looking to parse a .desc file with imports, this seemed to work for me:
FileInputStream fin = new FileInputStream(descPath);
DescriptorProtos.FileDescriptorSet set = DescriptorProtos.FileDescriptorSet.parseFrom(fin);
List<FileDescriptor> dependencyFileDescriptorList = new ArrayList<>();
for(int i=0; i<set.getFileCount()-1;i++) {
dependencyFileDescriptorList.add(Descriptors.FileDescriptor.buildFrom(set.getFile(i), depndencyFileDescriptorList.toArray(new FileDescriptor[i]));
}
FileDescriptor desc = Descriptors.FileDescriptor.buildFrom(set.getFile(set.getFileCount()-1), dependencyFileDescriptorList.toArray(new FileDescriptor[0]));

JLine: File Completion doesn't work on Windows

I want to use JLine to build a simple CLI. But I ran into a problem. File name completer doesn't work properly on Windows.
When I enter 8> first C:\ and press tab, completer do nothing although it should display all subfolders.
Here is my code:
ArgumentCompleter completer1 = new ArgumentCompleter(
new StringsCompleter("first"),
new FileNameCompleter(),
new NullCompleter()
);
ArgumentCompleter completer2 = new ArgumentCompleter(
new StringsCompleter("second"),
new NullCompleter()
);
AggregateCompleter completer3 = new AggregateCompleter(
completer1, completer2
);
ConsoleReader console = new ConsoleReader();
console.addCompleter(completer3);
while (true) {
String line = console.readLine("8> ");
if (line.isEmpty()){
console.println();
}
}
Any ideas how to fix this?

Cannot access java.lang.String in script run in Rhino

I have problems accessing Java classes in JavaScript. Calling a code snippet
var String = Java.type("java.lang.String");
from Java via javax.script.ScriptEngine, yields follwing Error
Exception in thread "main" javax.script.ScriptException: sun.org.mozilla.javascript.internal.EcmaError: ReferenceError: "Java" is not defined. (path/to/string.js#1) in path/to/string.js at line number 1
at com.sun.script.javascript.RhinoScriptEngine.eval(RhinoScriptEngine.java:156)
at main.JsTest.main(JsTest.java:55)
Using non-Java classes in the script works fine, e.g. var value = a + b, where a and b are defined in a javax.script.ScriptContext.
This is the Java class that executes the script.
JsTest.java
public class JsTest
{
public static void main(String[] args) throws Exception
{
ScriptEngineManager sem = new ScriptEngineManager();
ScriptEngine se = sem.getEngineByExtension("js");
String script = "path/to/string.js";
File scriptFile = new File(script);
FileReader fr = new FileReader(scriptFile);
se.put(ScriptEngine.FILENAME, script);
ScriptContext sc = new SimpleScriptContext();
se.eval(fr, sc);
}
}

I have no idea where your Java.type is coming from, but the official documentation uses Packages.java or just java.
So your line should probably look like
var String = Packages.java.lang.String;

Meka api i want to integrate Meka in Java Eclipse

public class Evaluate {
public static void main(String args[]) throws Exception{
//load datasets
DataSource source = new DataSource("F:/data/solar_flare.arff");
Instances dataset = source.getDataSet();
BufferedReader reader = new BufferedReader(new FileReader("F:/data/solar_flare.arff"));
Instances training = new Instances(reader);
reader = new BufferedReader(new FileReader("F:/data/solar_flare.arff"));
Instances testing = new Instances(reader);
J48 jjjj = new J48();
MultilabelClassifier PS = new PS();
PS.setClassifier(jjjj);
PS.setOptions(Utils.splitOptions("-threshold PCut1 -verbosity 3"));
PS.buildClassifier(training);
Evaluation ecal = new Evaluation(training);
ecal.evaluateModel(PS, testing);
dataset.setClassIndex(dataset.numAttributes()-1);
J48 tree = new J48();
tree.buildClassifier(dataset);
Evaluation eval = new Evaluation(dataset);
Random rand = new Random(1);
int folds = 10;
DataSource source1 = new DataSource("F:/data/solar_flare.arff");
Instances testDataset = source1.getDataSet();
testDataset.setClassIndex(testDataset.numAttributes()-1);
eval.crossValidateModel(tree, testDataset, folds, rand);
System.out.println(eval.toMatrixString("=== Confusion Matrix ===\n"));
}
}
This my Code its give error back
This is error
"Exception in thread "main" java.lang.NoSuchMethodError:
weka.core.Attribute.(Ljava/lang/String;Ljava/util/List;)V at
meka.core.PSUtils.PSTransformation(PSUtils.java:416) at
meka.classifiers.multilabel.PS.buildClassifier(PS.java:225)" at
Evaluate.main(Evaluate.java:57)

This is a typical error when you are using a library with a version that does not correspond to what you expect. You have to make sure the weka.core.Attribute exists in your version with the specified method.

Cannot load ImageIcon in JLabel - Java, Swing

I have a question that has been boring me for some days.
I'm implementing some swing interfaces that is supposed to load an image:
When i press a button it triggers an event that calls the following method:
private void GetDataPanelGeral()
{
ArrayList<String> Files = new ArrayList<>();
java.util.Date selectedDate = (java.util.Date) this.JDatePickerImpl_GERAL_MUDANÇAS_datePicker_START.getModel().getValue();
java.sql.Date sqlDateINICIO = new java.sql.Date(selectedDate.getTime());
selectedDate = (java.util.Date) this.JDatePickerImpl_GERAL_MUDANÇAS_datePicker_END.getModel().getValue();
java.sql.Date sqlDateFIM = new java.sql.Date(selectedDate.getTime());
//CALL MODULE 5
RunningLoop loop = null;
Thread t = new Thread
(
loop = new RunningLoop(50000,this.StringDBName,this.StringDBDriver,
this.StringDBUser,this.StringDBPass,this.PathToData,
sqlDateINICIO.toString(),
sqlDateFIM.toString(),
true)
);
t.start();
loop.StopLooping();
this.ImageLabelGERALMUNDANCAS.revalidate();
this.ImageLabelGERALMUNDANCAS.repaint();
this.ImageLabelGERALMUNDANCAS = new JLabel(new ImageIcon("this.PathToData+"/Results/Outputs/P5/0.png",""));
this.ImageLabelGERALMUNDANCAS.repaint();
JPanel Aggregator = new JPanel();
Aggregator.add(this.ImageLabelGERALMUNDANCAS);
Aggregator.setBackground(this.color);
//this.Aggregatorr.add(this.ImageLabelGERALMUNDANCAS);
this.JPanel_TABGeral.remove(1);
this.JPanel_TABGeral.add(Aggregator,1);
this.JPanel_TABGeral.revalidate();
this.JPanel_TABGeral.repaint();
Aggregator.revalidate();
Aggregator.repaint();
}
the image loaded in the line this.ImageLabelGERALMUNDANCAS = new JLabel(new ImageIcon("this.PathToData+"/Results/Outputs/P5/0.png","")); is created by a module called in the lines
//CALL MODULE 5
RunningLoop loop = null;
Thread t = new Thread
(
loop = new RunningLoop(50000,this.StringDBName,this.StringDBDriver,
this.StringDBUser,this.StringDBPass,this.PathToData,
sqlDateINICIO.toString(),
sqlDateFIM.toString(),
true)
);
t.start();
loop.StopLooping();
it seems to be all ok but it does not load the image.. If i try to load another image it works perfectly so i think the problem is the creation of the image in the thread.
Can somebody help me?
Ps: I'm still need to work in some code, currently i'm trying everything to get this work, then i'll worry about better code
Kind regards
