将库添加到jar中

标签： java file deployment jar auto-update

我已经制作了一个程序而且我想发布它但是我有5-6个HTTP库（.jar）用于更新检查我如何将它们组合到一个文件中？

我已经尝试过eclipse胖罐制造商，但它没有效果，当proram试图检查文件是否存在而且它没有找到它时，它会抛出一个eception。

文件获取代码：

public class NotesFile {

private File notesFile = new File("notes").getAbsoluteFile();;

public void saveNotes(String notes) {
    try {
        PrintWriter writer = new PrintWriter(new FileWriter(this.notesFile));
        writer.print(notes);
        writer.close();
    } catch (Exception ex) {
        ex.printStackTrace();
    }
}

public String getNotes() {
    String notes = "";
    try {
        if (!notesFile.exists()) {
            System.out.println("File loading failed ignoring load method.");
            return "";
        }

        BufferedReader reader = new BufferedReader(new FileReader(this.notesFile));

        String var1 = "";

        while ((var1 = reader.readLine()) != null) {
            notes = notes + var1 + "\n";
        }
        reader.close();
    } catch (Exception ex) {
        ex.printStackTrace();
    }
    return notes;
}}

例外：
