以编程方式在Eclipse中导入库 [英] Importing libraries in Eclipse programmatically

问题描述

有没有办法可以把一个库（Jar文件）编程到Eclipse项目中？到目前为止，我已经设法使用

  IPath path = new Path（C：\\ \\\myfolder\\mylibrary.jar）; 
 libraries.add（JavaCore.newLibraryEntry（path，null，null））; 
 //将libs添加到项目类路径
 try {
 javaProject.setRawClasspath（libraries.toArray（new IClasspathEntry [libraries.size（）]），null）; 
} catch（JavaModelException e1）{
 e1.printStackTrace（）; 
} 
  

然而，我想将jtwitter文件以编程方式复制到项目文件夹我可以将其引用为jtwitter.jar。可以这样做吗？

非常感谢，

解决方案

这样做了。我想要的是将库导入到项目中，然后从项目引用它，而不是使用对外部文件的引用。

  InputStream is = new BufferedInputStream（new FileInputStream（C：\\\myfolder\\mylibrary.jar） ）; 
 IFile file = project.getFile（mylibrary.jar）; 
 file.create（is，false，null）; 
 
 IPath path = file.getFullPath（）; 
 libraries.add（JavaCore.newLibraryEntry（path，null，null））; 
 //将libs添加到项目类路径
 try {
 javaProject.setRawClasspath（libraries.toArray（new IClasspathEntry [libraries.size（）]），null）; 
} catch（JavaModelException e1）{
 e1.printStackTrace（）; 
} 
  

Is there a way I could put a library (Jar file) into an Eclipse project programatically? Up to now I've managed to do an external reference to it programatically using

    IPath path = new Path("C:\\myfolder\\mylibrary.jar");
    libraries.add(JavaCore.newLibraryEntry(path, null, null));
    //add libs to project class path
    try {
        javaProject.setRawClasspath(libraries.toArray(new IClasspathEntry[libraries.size()]), null);
    } catch (JavaModelException e1) {
         e1.printStackTrace();
    }

However I'd like to copy the jtwitter file to the project folder programatically so I could reference it as jtwitter.jar only. Can this be done please?

Thanks a lot and regards, Krt_Malta

解决方案

This did the trick. What I wanted exactly is importing the library into the project and then referencing it from the project not using a reference to an external file.

    InputStream is = new BufferedInputStream(new FileInputStream("C:\\myfolder\\mylibrary.jar"));
    IFile file = project.getFile("mylibrary.jar");
    file.create(is, false, null);

    IPath path = file.getFullPath();
    libraries.add(JavaCore.newLibraryEntry(path, null, null));
    //add libs to project class path
    try {
       javaProject.setRawClasspath(libraries.toArray(new IClasspathEntry[libraries.size()]), null);
    } catch (JavaModelException e1) {
       e1.printStackTrace();
    }
