I am working on YouTube broadcast sample examples. I have created a sample Java Project & added required jars. But, when I try to run the project it throws exception.
Exception :
Throwable: com/fasterxml/jackson/core/JsonFactory java.lang.NoClassDefFoundError: com/fasterxml/jackson/core/JsonFactory at com.google.api.client.json.jackson2.JacksonFactory.<init>(JacksonFactory.java:44) at com.google.api.services.samples.youtube.cmdline.live.Auth.<clinit>(Auth.java:35) at com.google.api.services.samples.youtube.cmdline.live.CreateBroadcast.main(CreateBroadcast.java:55) Caused by: java.lang.ClassNotFoundException: com.fasterxml.jackson.core.JsonFactory at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) ... 3 more I downloaded the project from this GitHub repository.

You can fix NoClassDefFoundError error by checking following: Check the exception stack trace to know exactly which class throw the error and which is the class not found by java.
ClassNotFoundException occurs when you try to load a class at runtime using Class. forName() or loadClass() methods and requested classes are not found in classpath. Most of the time this exception will occur when you try to run an application without updating the classpath with JAR files.
Add the following dependency to your pom.xml
<dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>2.5.2</version> </dependency> If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
