Eclipse Select a project right-click--build path--configure Build path to open the configuration page for build path;
There will be four tab options
1.Source
This page is a directory of Java files that we need to compile, and the following "output folder" configures the location of the Java file's compiled class file.
We can add the Java file directory by adding the "Add Folder" button on the right, which is the file directory for adding this project.
We can also add the need to compile the Java file directory by the "Link Folder" button on the right, this can add a directory outside the home project, such as any folder on the computer
2,projects
I see someone else's explanation: associating to other items for a related search. This search, similar to path, has a range of functions.
My understanding is that related to other projects, and equivalent to the Mave in the Jar project, adding the other will be equivalent to the other projects to hit the jar package to import, you can use the class of the imported project.
3,libraries
Jar package, so the imported dependency jar packages are imported here.
The "Add Library" button on the right makes it easy to classify and manage dependent jar packages.
The "Add Class Folder" button on the right allows you to add the directory where the dependent class file resides.
4.Order and Export
Not surprisingly, the previous three configuration dependencies will be shown here.
Priority issues can be called, the higher the priority on the top call
When setting the export jar package, the contents of this library are also packaged in a jar, which is included and not included.
