Program runs fine in IDE but not as Jar file

Question

I have exported a jar file that I want to run the console. The code compiles and runs correctly in eclipse but I am having an issue running it from the console.

To me it looks like the referenced jar's I added via built path in the Eclipse project file and not being added to the export. If that is the case, how do I ensure that they do? If not, what am I doing wrong?

Answer 1

依赖关系必须在类路径上，即按以下方式运行：

java -cp <path_to_jar1>;<path_to_jar2> -jar ScrumTimeCaptureMaintenence.jar

Answer 2

从命令行运行时，请通过在-classpath参数中列出来确保在类路径上设置了任何依赖项

Answer 3

When you export your source code's class files to a jar using eclipse, only the .class files of your source are exported! Hence your exported jar file doesn't contain the referenced jars you mentioned in eclipse! Due to this, the error occurs while executing from command prompt.

Solution :
Take all the jar files required to execute the program, store it in the same directory as you store the exported jar file. Now while executing the java command, provide all the jar file's names in classpath field as following:

java -classpath .;JAR1.jar;JAR2.jar MainClass

Once you do this, your problem should be resolved!
