You cannot do this File src = new File(resourceUrl.toURI()); //ERROR HERE it is not a file! When you run from the ide you don’t have any error, because you don’t run a jar file. In the IDE classes and resources are extracted on the file system. But you can open an InputStream in this way: … Read more
The easiest way to do this would be to create an assembly using the maven-assembly-plugin and the predefined jar-with-dependencies descriptor. You’ll also need to generate a manifest with a main-class entry for this uber jar. The snippet below shows how to configure the assembly plugin to do so: <build> <plugins> <plugin> <artifactId>maven-assembly-plugin</artifactId> <configuration> <descriptorRefs> <descriptorRef>jar-with-dependencies</descriptorRef> … Read more
A jar file is simply a file containing a collection of java files. To make a jar file executable, you need to specify where the main Class is in the jar file. Example code would be as follows. public class JarExample { public static void main(String[] args) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { … Read more
Decompress the JAR file and look for the manifest file (META-INF\MANIFEST.MF). The manifest file of JAR file might contain a version number (but not always a version is specified).
You can try this: #!/bin/sh nohup java -jar /web/server.jar & The & symbol, switches the program to run in the background. The nohup utility makes the command passed as an argument run in the background even after you log out.
Actually, I think that the answer given in the question you mentioned is just wrong (UPDATE – 20101106: someone fixed it, this answer refers to the version preceding the edit) and this explains, at least partially, why you run into troubles. It generates two jar files in logmanager/target: logmanager-0.1.0.jar, and logmanager-0.1.0-jar-with-dependencies.jar. The first one is … Read more
If I understand correctly it appears you want to run the jars in a separate process from inside your java GUI application. To do this you can use: // Run a java app in a separate system process Process proc = Runtime.getRuntime().exec(“java -jar A.jar”); // Then retreive the process output InputStream in = proc.getInputStream(); InputStream … Read more
<build> <plugins> <plugin> <artifactId>maven-assembly-plugin</artifactId> <configuration> <archive> <manifest> <mainClass>fully.qualified.MainClass</mainClass> </manifest> </archive> <descriptorRefs> <descriptorRef>jar-with-dependencies</descriptorRef> </descriptorRefs> </configuration> </plugin> </plugins> </build> and you run it with mvn clean compile assembly:single Compile goal should be added before assembly:single or otherwise the code on your own project is not included. See more details in comments. Commonly this goal is tied to … Read more
I posted a solution in JIRA against Gradle: // Include dependent libraries in archive. mainClassName = “com.company.application.Main” jar { manifest { attributes “Main-Class”: “$mainClassName” } from { configurations.compile.collect { it.isDirectory() ? it : zipTree(it) } } } Note that mainClassName must appear BEFORE jar {.
I had encountered this issue when I had run my Jar file as java -jar TestJar instead of java -jar TestJar.jar Missing the extension .jar also causes this issue.
