PGP Encryption - Compile time issue

I am trying to PGP Encrypt a file using Java code. I have generated pgp keys (.asc file) for the same. Below is my Java code:
package extract;
import org.apache.camel.CamelContext;
import org.apache.camel.builder.RouteBuilder;
import org.apache.camel.impl.DefaultCamelContext;
public class PGPEncryption {
public static void main(String[] args) throws Exception {
String publicKeyFileName="abc-pub-sub.asc";
String keyUserid="abc";
String input_file_path="test.csv";
String output_file_path="/tmp/output";
camelContext.addRoutes(new RouteBuilder() {
public void configure() throws Exception {
from(input_file_path).marshal()
.pgp(publicKeyFileName, keyUserid).to(output_file_path);
}
});
camelContext.start();
Thread.sleep(5000);
camelContext.stop();
}
}
Below are the Jars I added in my build Path :
bcpg-jdk15on-1.56.jar
bcprov-jdk15on-1.56.jar
camel-core-2.6.0.jar
camel-crypto-2.9.5.jar
commons-logging-1.2.jar
slf4j-api-1.7.25.jar
slf4j-nop-1.7.25.jar
But above code is giving me compile time error as below :
"The method pgp(String, String) is undefined for the type DataFormatClause<ProcessorDefinition<RouteDefinition>>"
Could someone please help me in fixing this ?
Also I tried to export my code as Runnable Jar with compile time errors. But after I execute my Jar file I am facing below error:
Exception in thread "main" java.lang.NoClassDefFoundError: org/fusesource/commons/management/ManagementStrategy
I am not sure if I am missing any basic thing here. Could someone please help here? Thanks in Advance.

React Native: error: cannot find symbol > new AppCenterReactNativeAnalyticsPackage(MainApplication.this

I was getting a successful build with android in React Native until I added these:

"appcenter-crashes": "2.1.0",
I am on:
"react": "16.8.6",

Apparently there is this android/app/build/generated/rncli/src/main/java/com/facebook/react/PackageList.java file that did not exist with the legacy version of this application:

The MainApplication.java file is inside of android/main/java/com/nfibengage/MainApplication.java:

SoLoader.init(this, /* native exopackage */ false);
}
}
I tried importing it into PackageList.java like so:
import com.nfibengage.MainApplication;
but I continue to get the same error. If anyone can walk me through where did this PackageList.java file come from and how do I get this working again short of just completely removing appcenter-analytics and appcenter-crashes.

Please make sure your installation order is the same as the following.
Add the App Center SDK modules
npm install appcenter appcenter-analytics appcenter-crashes --save-exact
or
yarn add appcenter appcenter-analytics appcenter-crashes --exact
Integrate the SDK automatically
react-native link appcenter
react-native link appcenter-analytics
react-native link appcenter-crashes
App Center SDK does not set up mocks automatically for App Center modules during the linking process. If you are using Jest test framework in your application and experience errors caused by the App Center SDK while running tests with Jest, add the following to the jest section of package.json file (include only modules in use):
"setupFiles": [
"<rootDir>/node_modules/appcenter/test/AppCenterMock.js",
"<rootDir>/node_modules/appcenter-analytics/test/AppCenterAnalyticsMock.js",
"<rootDir>/node_modules/appcenter-crashes/test/AppCenterCrashesMock.js",
"<rootDir>/node_modules/appcenter-push/test/AppCenterPushMock.js"
]
Edit the project's android/app/src/main/assets/appcenter-config.json and replace the YOUR_APP_SECRET placeholder value with your App Center project's application secret.

do one think only
goto your folder structure.
2.Add a file yarn-error.log
there will not be any problem your project will start well.

org.bukkit.plugin.InvalidPluginException: java.lang.NoClassDefFoundError - Unirest

after some work on a spigot plugin IntelliJ itself doesn't give an error, however upon the jar build (when loaded into the server) the console prints an unirest callback error.
The project uses the spigot dependency for 1.13.2.
Code:
import com.mashape.unirest.http.HttpResponse;
import com.mashape.unirest.http.JsonNode;
import com.mashape.unirest.http.Unirest;
import com.mashape.unirest.http.async.Callback;
import com.mashape.unirest.http.exceptions.UnirestException;
import org.bukkit.plugin.java.JavaPlugin;
public class Weather extends JavaPlugin {
#Override
public void onEnable() {
// Plugin startup logic
getServer().getScheduler().runTaskTimer(this, () -> Unirest.get("https://data.buienradar.nl/2.0/feed/json").asJsonAsync(new Callback<JsonNode>() {
#Override
public void completed(HttpResponse<JsonNode> response) {
getServer().broadcastMessage(response.getBody().toString());
getLogger().info(response.getBody().toString());
}
#Override
public void failed(UnirestException e) {
e.printStackTrace();
}
#Override
public void cancelled() {
}
}), 0, 20 * 30);
}
}

org.bukkit.plugin.InvalidPluginException: java.lang.NoClassDefFoundError - Unirest means, that the class Unirest is not found at runtime. A common mistake is, that you have added the library containing the class Unirest as dependency, but the library does not get exported with your plugin. So, make sure, that when you export your plugin, the library containg the class Unirest is also included in the resulting jar file.

Java Tesseract dyld: Symbol not found:

im trying to do simple OCR application but i get errors like this:
Code:
import org.bytedeco.javacpp.*;
import static org.bytedeco.javacpp.lept.*;
import static org.bytedeco.javacpp.tesseract.*;
import static org.junit.Assert.assertTrue;
import java.io.File;
import java.io.UnsupportedEncodingException;
public class Main {
public void tesseract(String filename){
BytePointer outText;
tesseract.TessBaseAPI api = new tesseract.TessBaseAPI();
// Initialize tesseract-ocr with English, without specifying tessdata path
if (api.Init("/Users/Marcel/tesseract-ocr", "ENG") != 0) {
System.err.println("Could not initialize tesseract.");
System.exit(1);
}
// Open input image with leptonica library
PIX image = pixRead(filename);
api.SetImage(image);
// Get OCR result
outText = api.GetUTF8Text();
String string = outText.getString();
assertTrue(!string.isEmpty());
System.out.println("OCR output:\n" + string);
// Destroy used object and release memory
api.End();
outText.deallocate();
pixDestroy(image);
}
public static void main(String[] args) {
Main main = new Main();
String fileName = "src/main/resources/test.png";
main.tesseract(fileName);
}
}
I have tried some solutions from google, but it didnt solve this. I using Inteliji (with maven) on Mac OSX. Before i had problem with TESTDATA_PREFIX, but i changed api.init first parameter and now i get this:
dyld: lazy symbol binding failed: Symbol not found: __ZN9tesseract11TessBaseAPI8SetImageEPK3Pix

This is because of 2 conflicting libtesseract.3.dylib.
If you have installed tesseract on mac using brew then it is referring to the libtesseract.3.dylib inside tesseract folder /usr/local/Cellar/tesseract/3.04.01_1/lib/
instead of /usr/local/lib/libtesseract.3.dylib

GXT 3 XTemplate: Custom Formatter - ClassNotFoundException

I am trying to use a custom formatter to turn a boolean into "Yes" or "No" and have run into a roadblock.
My IDE (Eclipse) does not indicate any errors but when I try to compile I receive
[ERROR] Annotation error: cannot resolve foobar.client.formatter.YesNoFormatter - exception: ClassNotFoundException
followed by a few other exceptions that appear to stem from this exception. I understand what a ClassNotFoundException indicates however I cannot figure out why I would be getting it since, as my code shows, the YesNoFormatter class is located in foobar.client.formatter and I can access it through
GWT.log("True: " + YesNoFactory.getFormat().format(Boolean.TRUE);
I am using GXT 3.1.0 and GWT 2.6.1.
Could anybody have an idea of why I am getting this exception? The example given at http://docs.sencha.com/gxt-guides/3/utility/xtemplates/XTemplates.html doesn't mention anything (as far as I can see) about these classes needing to be in specific locations so I am at a loss.
EntryPoint:
package foobar.client;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.core.client.GWT;
import com.google.gwt.safehtml.shared.SafeHtml;
import com.sencha.gxt.core.client.XTemplates.FormatterFactories;
import com.sencha.gxt.core.client.XTemplates.FormatterFactory;
public class TestClass implements EntryPoint {
#FormatterFactories(#FormatterFactory(factory=YesNoFactory.class, name="yesNo"))
public interface Renderer extends XTemplates {
#XTemplate(source="yesNo.html")
SafeHtml render(Boolean b);
}
#Override
public void onModuledLoad() {
GWT.log("True: " + YesNoFactory.getFormat().format(Boolean.TRUE);
Renderer r = GWT.create(Renderer.class);
Window.alert(r.render(true).asString());
}
}
YesNo:
package foobar.client.formatter;
import com.sencha.gxt.core.client.XTemplates.Formatter;
public class YesNo implements Formatter<Boolean> {
#Override
public String format(Boolean data) {
if (data == null) {
return null;
}
return (data) ? "Yes" : "No";
}
}
YesNoFactory:
package foobar.client.formatter;
public class YesNoFactory {
public static YesNo getFormat() {
return new YesNo();
}
}
in foobar
<?xml version="1.0 encoding="UTF-8"?>
<module>
<inherits name='com.google.gwt.user.User'/>
<inherits name='com.sencha.gxt.GXT'/>
<entry-point class='foobar.client.TestClass'/>
<source path='client'/>
</module>
foobar/client/yesNo.html:
{b:yesNo()}

My formatter classes (YesNo and YesNoFactory) apparently have to be in a location that gets compiled prior to compiling the client-side code. After I moved these classes to my 'shared' package - the package that houses code used by the client and server - everything worked.
This was not obvious in the XTemplates portion of the guide at http://docs.sencha.com/gxt-guides/3/utility/xtemplates/XTemplates.html which does not seem to specify where the files used for custom formatters need to be located. Maybe that should have been obvious but not to me.
