I can create a runnable jar every time with Eclipse's Runnable Jar wizard. If I check the box for Eclipse to "Save as ANT script", then incorporate that code into build.xml and then have our GitLab CI process do a build & create a runnable jar, it runs, but it can't seem to find a class in that jar even though the .class file is in there.
I'm not sure where to start. The resulting jar files from the Eclipse build vs the standalone java/ant build are similar, but not exactly the same. A few things are out of order, but that's all I can put my finger on at the moment.
How can I start to hone in on this? My program is a Jersey web client. I'm using Genson and the error message I'm getting with the standalone jar build is
org.glassfish.jersey.message.internal.MessageBodyProviderNotFoundException: MessageBodyWriter not found for media type=application/json
But I can list the jar files and both have these entries
47 Sun Mar 27 22:23:48 CDT 2016 META-INF/services/javax.ws.rs.ext.MessageBodyWriter
1220 Thu Aug 07 14:08:08 CDT 2014 javax/ws/rs/ext/MessageBodyWriter.class
Right now I can get around it by doing a build in Eclipse and manually deploying the file, but of course this isn't acceptable.
EDIT: Thanks to a helpful friend, I was pointed to the contents of META-INF/services. I don't know what it means, but here are the contents of that from both jars.

Thanks all.
I was using an older Kafka version.
I upgraded Kafka in the cluster from kafka_2.12-1.1.0 to the latest stable version kafka_2.12-2.7.0. I also upgraded zookeeper from zookeeper-3.4.6 to apache-zookeeper-3.6.2-bin version.
In addition in the run file I added the following:
#!/bin/ksh
unset CLASSPATH
export CLASSPATH=/d4T/hduser/bigquery-kafka-connect-sink/share/kafka/plugins:$KAFKA_HOME/libs
$KAFKA_HOME/bin/connect-standalone.sh \
/d4T/hduser/bigquery-kafka-connect-sink/etc/connect-standalone.properties \
/d4T/hduser/bigquery-kafka-connect-sink/etc/bigquery-sink.properties
where the first part of CLASSPATH comes from plugins
plugin.path=/d4T/hduser/bigquery-kafka-connect-sink/share/kafka/plugins
This solved the issue
I've got a problem which I understand but I have no idea how to fix it.
I have a class in my project that contains static fields with images or sounds so that I can use them everywhere without recreating variables every time.
One of the fields for reference (they are all the same):
public static ImageIcon mainMenuBg = new ImageIcon(Resources.class.getResource("img/menubg.png"));
Now my problem is that it works fine in Eclipse when I run it, but when I export the project to a runnable JAR, nothing happens. I then went in the command window and ran it from there, and I have this ExceptionInInitializerError due to my images. Basically, none of the images are recognized at runtime, so if I remove every image call, it works.
Also, it is worth noting that when exporting, the list of Main classes doesn't really update. If I change the project's main's name, it isn't added to the list. Might it be a problem with my main class specifically? If so, how can I fix that? I tried to recreate it already but nothing changed.
Could someone enlighten me about this problem, please?

Also, all of my classes are in the same package, the default one.
Finally, here is the 'jar tvf ...' command's result:

After digging in documentation around I think that is possible that the problem is that you are using a relative path instead of an absolute path as explained here:
[http://www.thinkplexx.com/learn/howto/java/system/java-resource-loading-explained-absolute-and-relative-names-difference-between-classloader-and-class-resource-loading]
So please try:
ImageIcon mainMenuBg = new ImageIcon(Resources.class.getResource("/img/menubg.png"));
Use somthing like this for your images.
ClassLoader cldr = this.getClass().getClassLoader();
URL picture = cldr.getResource("files/gcf.jpg");
ImageIcon mainMenuBg = new ImageIcon(picture);
And for the sounds.
ClassLoader cldr = this.getClass().getClassLoader();
URL musicurl = cldr.getResource("files/gcf.wav");
try{
AudioInputStream audioInputStream = AudioSystem.getAudioInputStream(musicurl);
Clip clip = AudioSystem.getClip();
clip.open(audioInputStream);
clip.start();
}
catch (Exception ex){
System.out.println("loading ??");
}
(import java.net.*; for the URL class)
Put your /files folder into the /src folder and create your JAR.
I have module structure like
external_services/pom.xml
ifs/pom.xml
src/main/java
src/main/java/resources
src/test/java
src/test/java/resources/sample.json
inventory/pom.xml
ifs/pom.xml
src/main/java
src/main/java/resources
src/test/java/MyTest.java
In this MyTest.java I need to get sample.json since I want that to be shared across, so in business/pom.xml I add the following
<dependency>
<groupId>com.org.my_services.external_services</groupId>
<artifactId>ifs</artifactId>
<version>1.0-SNAPSHOT</version>
<type>test-jar</type>
<scope>test</scope>
</dependency>
so now when I run the test, I see
file:/Users/harith/.m2/repository/com/org/my_services/external_services/ifs/1.0-SNAPSHOT/ifs-1.0-SNAPSHOT-tests.jar!/sample.json (No such file or directory)
However, when I look at jar ifs-1.0-SNAPSHOT-tests.jar, I see it there
jar -tvf /Users/harith/.m2/repository/com/org/pryme_services/federated_services/ifs/1.0-SNAPSHOT/ifs-1.0-SNAPSHOT-tests.jar

The way it is used in class is
inventoryPriceDetails = mapper.readValue(new File(getClass().getResource("/getInventoryAndPrice.json").getPath()), new TypeReference<List<InventoryPriceDetail>>() {
});
I am not sure what I am missing, can some one please help?
there are a couple of things:
1)
external_services/pom.xml
ifs/pom.xml
src/main/java
src/main/java/resources
src/test/java
src/test/java/resources/sample.json
but maven expects
external_services/pom.xml
ifs/pom.xml
src/main/java
src/main/resources
src/test/java
src/test/resources/sample.json
"resource" parallel to "java". In your case "resource" is a package.
2) The file is called "sample.json" but you look for "getInventoryAndPrice.json"
3) new File does not work on a Path. You need getResourceAsStream() to extract data from a jar.
(If you want to work with paths you need to work with the nio classes, not File)
My group publishes executable jars (not applets, just to be clear) for nearly all of our functionality. One of our new executables is a Web service client that relies on Jersey. I'm trying to use the automatic POJO mapping facility to unmarshal responses (i.e., I have JSONConfiguration.FEATURE_POJO_MAPPING set to true in the ClientConfig) but when I execute the jar I get the "I don't know how to unmarshal this response" message:
SEVERE: A message body reader for Java class edu.mit.broad.picard.bass.GetSite, and Java type class edu.mit.broad.picard.bass.GetSite, and MIME media type application/json was not found
The app works just fine if I run it from my IDE (IntelliJ). I'm assuming it's a problem with the way in which the jar file is packaged but I don't know the details of Jersey (or Jackson, for that matter) well enough to get this fixed. Any hints?
This is Java 1.7, Jersey bundle 1.17.1 and Jackson 1.9.13. All the com/sun/**/* and org/codehaus/**/* files are being included in the jar.
Thanks for your help!!
Edit:
I checked the META-INF dir for the needed .../services dir. Here's what's in it:

My guess would be that you are creating one jar that contains the contents of all of your jar dependencies. If this is the case, the issue is probably due to improper construction of your one jar. Jersey relies on resources in META-INF/services for its proper operation. You need to make sure that the contents of META-INF/services get merged into your one jar.
One option that is working for me is the maven-shade-plugin, which includes a transformer that does exactly this merging:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<configuration>
<transformers>
<transformer implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer" />
</transformers>
</configuration>
</plugin>
I have an issue which has been bothering me for days... I checked similar questions but couldn't find a solution.
I use NetBeans IDE. I build the project jar file i.e "Clock.jar" which contains a "clock" named folder in which some images, a text file and all project classes are found.
The following code for creating an image icon works
return new ImageIcon(getClass().getResource("/clock/button_close.png"));
But the following code for reading the text file fails
InputStream name = getClass().getResourceAsStream("/clock/input.txt");
BufferedReader reader = new BufferedReader(new InputStreamReader(name));
As you may have guessed the NullPointer Exception is thrown meaning probably it couln't locate the file.
But how come the image icon is constructed successfully (by passing it the URL returned from getResource) but the txt file cannot be found (by passing it an input stream from getResourceAsStream).
Thanks in advance, for any answer ( I mean it :) )

Looking at the source again closely, try..
URL url = getClass().getResource("/clock/input.txt");
InputStream name = url.openStream();
I recall that the Class::getResourceAsStream variant deals with paths slightly differently than simply Class::getResource - I am sure it should work for the latter one.
