Eclipse是否可以像多个源文件夹一样具有多个输出文件夹 [英] Can Eclipse have multiple output folders just like multiple source folders

问题描述

我有一个Eclipse项目，其中有两个源文件夹- src和 test。我希望将这两个文件夹中的内容放入单独的输出文件夹中。

I have an Eclipse project, which has two source folders - 'src', and 'test'. I would like the build from both these folders to go into separate output folders.

原因是，这两个文件夹都有一个名为ServiceProviders.properties的属性文件，该文件具有不同的值用于代码的生产和测试运行。

The reason being, both these folders have a property file called ServiceProviders.properties which has different values for production and test runs of the code.

问题是，由于只有一个输出文件夹可以复制所有编译的类，因此不会复制'test'中的属性文件，因此我测试代码获取属性文件的生产版本。我想我正在尝试模拟在Maven中具有不同类路径的方式（及其查找顺序）。

The problem is, since there is only one output folder where all compiled classes are copied, the properties file in 'test' does not get copied, and as a result my test code gets the production version of the properties file. I guess I am trying to simulate the way we can have different classpaths in Maven (and their lookup order).

如果这不起作用，我将使用JVM属性指定可以在测试用例中使用的某些值。但是，这似乎不是一个很好的解决方案。

If this does not work, I will use a JVM property to specify certain values which I can use in the test case. However, it does not seem like an elegant solution.

使用Maven可以使它工作，但是我不能在该项目中使用Maven。

Using Maven will get this to work, but I cannot use Maven in this project.

更新1：

感谢您的回答。由于它们是相同的，因此我接受了之前发布的内容。

Thanks for both the answers. Since they were identical, I have accepted the one which was posted earlier.

Upadte 2：

即使我可以为对应的源文件夹获得多个输出文件夹，它也不能解决我原来的问题，即在运行测试用例时从测试加载ServiceProviders.properties，而在运行测试用例时从src加载Eclispe服务器上的应用程序。我使用它的方法是通过从测试文件夹中使用ServiceProviders.properties文件创建一个单独的jar文件。在测试用例的运行配置中，我添加了这个jar文件并更改了顺序，因此它似乎是查找的第一个依赖项。

Even though I could get multiple output folders for corresponding source folders, it did not solve my original problem which was to load a ServiceProviders.properties from test when I run test cases, and the one from src when I run the app on a server from Eclispe. The way I got it to work is by creating a separate jar file with ServiceProviders.properties file from the test folder. In the run configuration of my test cases, I add this jar file and change the order, so it appears as the first dependency for lookup.

推荐答案

是的，我刚刚检查了一下。
如果进入项目的属性，然后进入Java Build Path，从中选择不同的Source-Folders，则还有一个名为允许源文件夹的输出文件夹的选项，如果选中该选项，则会添加一个每个源文件夹的可编辑输出文件夹。
只需选择它，然后单击编辑按钮，就可以了

Yes it can, i just have checked that. If you go into Properties of your Project, and there to Java Build Path, where you choose your different Source-Folders, there also is an option called "Allow output folders for source folders", which, if checked adds an editable output-folder for each of your source-folders. just select it and click the edit-button and you're fine
