Get the target directory path in Maven (Java)
提问by vkrams
In a Maven project I want write some test results into a file in target directory of the project. Whenever, I get the project directory, it is actually getting the IntelliJ project directory instead of actual Maven directory.
在 Maven 项目中，我想将一些测试结果写入项目目标目录中的文件中。每当我获取项目目录时，它实际上是获取 IntelliJ 项目目录而不是实际的 Maven 目录。

I got the solution for this. Here is how I am implementing. I have my own class CSVReader which uses CSVReader library. I am writing my results in results.csv file under target directory.
我得到了解决方案。这是我的实施方式。我有自己的类 CSVReader，它使用 CSVReader 库。我正在将结果写入目标目录下的 results.csv 文件。
URL location = CSVReader.class.getProtectionDomain().getCodeSource().getLocation();
String path = location.getFile().replace("classes/","") + "results.csv";
In the above code I am getting the target directory path and removing the classes/ by string replace method and appending my desired file name. Hope this might help someone.
在上面的代码中，我正在获取目标目录路径并通过字符串替换方法删除 classes/ 并附加我想要的文件名。希望这可以帮助某人。

You could also use java.nio.file.Paths:
您还可以使用java.nio.file.Paths：
URL url = Paths.get("target", "results.csv").toUri().toURL();

I used the answer above with a slight modification (I can't add comments). Since tests are placed into the 'test' folder, their classes will reside in 'target/test-classes' (so replacing 'classes' might not give you the expected result). Instead, I used the following:
我稍微修改了上面的答案（我无法添加评论）。由于测试放置在“test”文件夹中，它们的类将驻留在“target/test-classes”中（因此替换“classes”可能不会给您预期的结果）。相反，我使用了以下内容：
File targetClassesDir = new File(ExportDataTest.class.getProtectionDomain().getCodeSource().getLocation().getPath());
File targetDir = targetClassesDir.getParentFile();
