在类路径中包含jar文件

Question

我从一个批处理文件中运行一个java程序，它重新添加了一些外部jar文件。如何在我的批处理文件中包含这些jar文件。请帮助

Answer 1

Look at the Sun's official documentation: Setting the class path to understand your options.

A quick way would be just to include your JAR(s) after the -cp :

on Windows

java -cp C:\java\MyClasses\myclasses.jar;C:\java\MyClasses\myclassesAnother.jar utility.myapp.Cool

on Linux/Unix

java -cp /opt/thirdparty/myclasses.jar:/opt/thirdparty/myclassesAnother.jar utility.myapp.Cool

Answer 2

You need to set classpath http://download.oracle.com/javase/1.3/docs/tooldocs/win32/classpath.html . Eg,

java -cp file1.jar;file2.jar yourApp

or if your jar-files are located in directory lib/

java -cp lib/* yourApp

Answer 3

Not to bother with -classpath parameter you could put references to the jar files into the manifest.mf of your application JAR, if it's you application of course.

Adding Classes to the JAR File's Classpath

Answer 4

You have to fill the Class-Path parameter of the manifest file of the JAR. The standard documentation explains that very well.

Answer 5

Sorry, I dont know others IDE, but works with me on Eclipse.
Right click on your project, select

Properties/ Java Build Path/ Libraries/ Classpath/ Add External JARs...

Then choose whatever files you need :v
