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.

Please HELP!!
I'm working on an app in react-native that involves using a native Calendar module. I'm trying to register this module with react native and I keep getting this error.
This is how I've registered the module in MainApplication.java:
#Override
protected List<ReactPackage> getPackages() {
List<ReactPackage> packages = new PackageList(this).getPackages();
packages.add(new ModuleRegistryAdapter(mModuleRegistryProvider));
packages.add(new MyAppPackage());
return packages;
}
This is the MyAppPackage.java file I've created using the tutorial here, https://reactnative.dev/docs/native-modules-android#register-the-module-android-specific.:
package com.chowtime; // replace your-app-name with your app’s name
import com.facebook.react.ReactPackage;
import com.facebook.react.bridge.NativeModule;
import com.facebook.react.bridge.ReactApplicationContext;
import com.facebook.react.uimanager.ViewManager;
import java.util.ArrayList;
import java.util.Collections;
import java.util.List;
public class MyAppPackage implements ReactPackage {
#Override
public List<ViewManager> createViewManagers(ReactApplicationContext reactContext) {
return Collections.emptyList();
}
#Override
public List<NativeModule> createNativeModules(
ReactApplicationContext reactContext) {
List<NativeModule> modules = new ArrayList<>();
modules.add(new CalendarModule(reactContext));
return modules;
}
}
Note: This app was previously created using the managed-workflow on expo and was ejected to the bare workflow. This is the directory for the relevant files:
I came across this same error. It seems like the docs on how to create/use native modules in react native are missing a step.
In the MainApplication.java file you need to import 'MyAppPackage'.
import com.your-app-name.MyAppPackage;
Without importing it the 'MainApplication' file it won't know what MyAppPackage is referring to hence the cannot find symbol error.
Is this as simple as an import problem?
I noticed your MyAppPackage class is defined here:
package com.chowtime; // replace your-app-name with your app’s name
But your MainApplication error message seems indicate a sub-package, specifically "chowtime.chowtime". Did you mean for both chowtimes?
com.chowtime.chowtime.MainApplication
I am trying to send OSC (Open Sound Control) to Figure 53's QLab. So far I have come up with this code.
import com.illposed.osc.transport.udp.OSCPortOut;
import com.illposed.osc.OSCMessage;
import java.io.IOException;
import java.net.InetAddress;
import java.net.UnknownHostException;
public class controller {
public static void main(String[] args) throws UnknownHostException, IOException {
OSCPortOut sender = new OSCPortOut(InetAddress.getByName("10.67.192.113"), 53000);
OSCMessage msg = new OSCMessage("/cue/1");
try {
sender.send(msg);
} catch (Exception e) {
e.printStackTrace();
}
}
}
I have successfully added Illposed's JavaOSC library to my code, but then it says I need SLF4J, and when I try to add slf4j-api-1.7.30.jar it says Failed to load class "org.slf4j.impl.StaticLoggerBinder". When I try to run the above code with both libraries SLF4J and JavaOSC.
You will need to use Maven to handle the dependencies JavaOSC needs.
Here's a good tutorial for Eclipse. Just use a simple project, you do not need to do archetype selection.
Then add the following at the end of your new projects pom.xml file, before
</project>
but after everything else.
`<dependency>`
<groupId>com.illposed.osc</groupId>
<artifactId>javaosc-core</artifactId>
<version>0.7</version>
</dependency>
I was getting a successful build with android in React Native until I added these:
"appcenter-analytics": "2.1.0",

I am on:

"react-native": "0.60.4",
The error is:

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.
I have a requirement to capture photos using system webcam. For this, I'm using webcam capture library. It contained three jar files. I wanted to package every thing including dependency jars in single jar application.
So, I sorted to unpack the dependent jar files place them in the src folder of netbeans project.
So, I extracted them. Two of them start with the same package name org, so I extracted and merged them. Important third package starts with com package. I've placed these three directories in src folder of my netbeans project.
Now the problem is that netbeans, says that package doesn't exist. But, the same project when compiled from command line in windows. It compiled and ran successfully, everything was working fine.
But, when I added the problematic library as a jar to the project, it worked fine, only extracting and placing it in src folder causing the problem.
Why is this error occurring and why in netbeans only, how to resolve this problem?
My code:
package screen;
import com.github.sarxos.webcam.*; **//Error here**
import com.github.sarxos.webcam.log.*; **// Error here**

ImageIO.write(image,type,new File(filePath+"_"+date.toString().replace(' ','_').replace(':','-')+"."+type.toLowerCase()));
webcam.close();
}

}

I am new to GWT and trying to build a sample application. Here is my EntryPoint class.
package com.google.gwt.sample.client;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.core.client.GWT;
public class TalkToServer implements EntryPoint {
public TalkToServer() {}
public void onModuleLoad() {
HTTPRequest.asyncGet
(GWT.getHostPageBaseURL() + "person.xml",
new ResponseTextHandler() {
public void onCompletion(String responseText) {
GWT.log("some log message");
}
});
}
}
The error here is -
log(java.lang.String,java.lang.Throwable) in com.google.gwt.core.client.GWT cannot be applied to (java.lang.String)
I have checked gwt's javadoc and found that log can take string as argument. I am not able to figure out why log is throwing this error. Please let me know if I am missing something.
Try using
GWT.log("some log message", new Throwable())
