问题 I am getting the following error when I am trying to use the library during runtime: java.lang.NoClassDefFoundError: com.google.api.client.extensions.android2.AndroidHttp I have added this library to my project, it is the first jar of the Maven dependencies( I am not 100% used to Maven though). Also,My understanding is that Ant is looking for the jars in a libs folder, but Maven is using its own folder, and that works fine for an other project. So I am lost..any clues/help on how should I

问题 I am trying to run a very simple ActiveMQ client script in GroovyConsole. I've included activemq-all-5.5.0.jar and slf4j-api-1.5.11.jar through the Script > Add Jar to ClassPath menu. I see org.apache.activemq.ActiveMQPrefetchPolicy in the activemq jar, yet I am getting the exception below. Here is the script: import org.apache.activemq.* import org.apache.activemq.command.* import javax.jms.* // // // def connectionFactory = new ActiveMQConnectionFactory("tcp://localhost:61616") def

问题 So this question is going to be somewhat vague, and I apologize, but I don't really even know where to start. We use Jenkins to automate some builds during the night. We execute our builds with maven. For a while, everything was working out nice. We had findbugs, and code coverage results and a steady history of successful builds. All of the sudden, seemingly out of now where we are getting random NoClassDefFound exceptions while the unit tests are being run. Its very strange, because before

问题 I am trying to navigate to a fragmentactivity with a button click but my app crashes on the line it creates the intent. Can anyone help me figure out why? The activity I am navigating too is in the same package and I believe it is correctly recorded in the manifest. Here is my manifest <?xml version="1.0" encoding="utf-8" standalone="no"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.indigohate" android:versionCode="1" android:versionName="1.0" > <uses-sdk

问题 I have a Java Maven project that I developed a while ago and that doesn't work anymore. It uses a parent pom together with another Maven project in which I think the Jena version was changed and it also uses an external library that uses Jena. The Maven dependency is: <dependency> <groupId>com.hp.hpl.jena</groupId> <artifactId>jena</artifactId> <version>2.6.4</version> </dependency> When I execute my tests I get the following errors: java.lang.NoClassDefFoundError: Could not initialize class

问题 As many I get the following error: java.lang.noclassdeffounderror: com.google.android.gms.R$styleable when trying to implement Maps for Android V2. Somehow I must be missing what I exactly am doing wrong, since it's not working. What I tried first is to copy the google-play-services.lib into the lib folder, but I saw somewhere I shouldn't do this. Then I tried to import addon-google_apis-google-8 as a project, but the project gives the error The import com.google cannot be resolved. I'm

问题 I'm getting the NoClassDefFoundError after executing my project's JAR file. Debugging with Eclipse works fine, but I get this error whenever I use the windows command java -jar myproject.jar since I installed JDK 1.7. It was working fine using Java 1.6. Here's the error log : Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/log4j/Layout at program.Main.main(Main.java:20) Caused by: java.lang.ClassNotFoundException: org.apache.log4j.Layout at java.net.URLClassLoader$1.run
