Java / NetBeans - 如何进入一个jar文件？ [英] Java / NetBeans - How to Step into a jar file?

问题描述

我在Netbeans中有一个Java项目，它的库部分属性中列出了几个jar文件。

我发现了一个jar文件中的错误，我想

以下是我迄今为止所做的：

我已经找到
jar文件的源代码。

1. 我将这个源作为一个项目打开
   NetBeans（它以NetBeans
   项目）


2. 我从
   项目的
   编译时库部分删除了该jar文件。


3. 我使用add project在
   项目的
   编译时库中添加了新项目。


4. 在新的
   项目和我的项目。

它像以前一样构建和运行，但我仍然无法进入新项目的代码。但是当我尝试在新项目中进入一个方法时，Netbeans说无法打开（缺少源代码））。我还试图在新项目的方法中设置一个断点，但是Netbeans表示无法提交断点LineBreakpoint ObjectMakerFactory.java：203，原因：类中没有可执行位置203

解决方案

我不能说netbeans，但对于Eclipse和IntelliJ，我一直都有成功下载src jar并将其添加到项目中。然后，在我的代码中，当我点击jar中的类的方法，IDE将我带到源。如果发生这种情况，您可以在src中设置断点并正常进行。

I have a Java project in Netbeans with several jar files listed in its library section of properties.

I found a bug in one of the jar files and I want to step into it while debugging.

Here's what I've done so far:

1. I've found the source code for the jar file.
2. I opened that source as a project in NetBeans (it comes as a NetBeans project)
3. I deleted that jar file from the compile-time libraries section of my project.
4. I added the new project in the compile-time libraries section of my project using "add project".
5. Did a clean and build on the new project, and on my project.

It builds and runs the same as before but I still can't step into the new project's code. But when I try to step into a method in the new project Netbeans says "cannot open (missing source?)". I also tried to set a breakpoint in the new project's method but Netbeans says "Not able to submit breakpoint LineBreakpoint ObjectMakerFactory.java : 203, reason: No executable location available at line 203 in class ...."

解决方案

I cant say for netbeans, but for Eclipse and IntelliJ I've always had success downloading the src jar and adding it to the project. Then, in my code when I click into the method for a class in the jar the IDE brings me to the source. If that is happening, you can set breakpoints in the src and proceed as normal.
