Hey there! As someone who's navigated the early hurdles of using jsprit with Maven and GitHub, let me walk you through the two most reliable ways to get this library working smoothly for your project—no more invalid import errors or missing dependencies.

1. 优先用Maven官方依赖引入（最简单稳定） #

Your earlier issue with third-party JAR downloads makes total sense—those sites often serve incomplete or mismatched JARs that lack required dependencies. Lucky for you, jsprit is hosted on Maven Central, so you can skip third-party sites entirely:

• Open your project's pom.xml file, and add these dependencies inside the <dependencies> block:

<dependency>
    <groupId>com.graphhopper</groupId>
    <artifactId>jsprit-core</artifactId>
    <version>1.8.0</version> <!-- Use the latest stable version available on Maven Central -->
</dependency>
<!-- Add this if you need the visualization or analysis tools from the examples -->
<dependency>
    <groupId>com.graphhopper</groupId>
    <artifactId>jsprit-analysis</artifactId>
    <version>1.8.0</version>
</dependency>

• Save the file, then refresh your Maven project (in IDEs like IntelliJ, click the "Reload Maven Projects" icon). Maven will automatically download all the required JARs and their dependencies, so your import statements should work perfectly now.

2. 直接导入GitHub项目（适合需要修改源码或跑官方示例） #

If you want to tweak jsprit's code or run the official example projects directly, importing the GitHub repo as a module in your IDE is the way to go:

• Open your IDE (e.g., IntelliJ IDEA), go to File > New > Project from Version Control, enter the official jsprit repository address, and clone it to your local machine.
• Once cloned, add it as a module to your existing project: Right-click your project in the IDE sidebar, select Module Settings > Modules > + > Import Module, then choose the root folder of the cloned jsprit repo. Follow the wizard to complete the import.
• After importing, make sure your IDE recognizes the Maven configuration—this will ensure all dependencies are set up correctly, so you can run the example classes or reference jsprit code in your own project without issues.

Quick Pro Tips for Newbies #

• Stick with the Maven dependency method unless you specifically need to modify jsprit's source code—it's less error-prone and keeps your project clean.
• When running the official examples, double-check that your import paths match the version you're using (e.g., com.graphhopper.jsprit.core.* for version 1.8.0).
