intellij idea中Sources Root、ReSources Root等的区别 浅浅的花香味﹌ 2021-09-27 11:18 2617阅读 0赞 **1. Source roots (or source folders)** By assigning a folder to this category, you tell IntelliJ IDEA that this folder and its subfolders contain source code that should be compiled as part of the build process. **2. Test source roots (or test source folders; shown as rootTest)** These roots are similar to source roots but are for code intended for testing (e.g. for unit tests). Test source folders let you keep the code related to testing separate from the production code. Compilation results for sources and test sources, normally, are placed into different folders. **3. Resource roots** are for resource files used in your application (images, various configuration XML and properties files, etc.). During the build process, all the contents of the resource folders are copied to the output folder as is. Similarly to sources, you can specify that your resources are generated. You can also specify which folder within the output folder your resources should be copied to. **4. Test resource roots** (or test resource folders; shown as rootTestResourceIJ; available only in Java modules) are for resource files associated with your test sources. In all other respects, these folders are similar to resource folders. \*\*5. Excluded roots (shown as rootExcluded) are ones that IntelliJ IDEA “almost ignores”.\*\* Very limited coding assistance is provided for files in excluded folders. Classes contained in excluded folders don’t appear in code completion suggestion lists, references to such classes are shown in the editor as unresolved. When searching, IntelliJ IDEA doesn’t look in excluded folders, etc.
