编译ODL Controller路径及Yang Tools版本适配问题咨询

Hey there! Let's break down and fix your ODL Controller compilation problems one by one:

1. Correct Compilation Path #

The file structure of ODL Controller has indeed evolved over versions. When you clone the repo using git clone https://git.opendaylight.org/gerrit/p/controller.git, the root directory of the cloned controller folder is where you should run your compilation commands. You don't need to navigate into a deeper subdirectory like control... (that's likely a leftover path from older versions).

Just run:

cd controller

This will put you in the right place to start building.

2. Yang Tools Version Confusion #

You mentioned the requirement is Yang Tools ≥0.5.8-SNAPSHOT, but your downloaded code uses 0.8.0. Don't worry—0.8.0 is a newer, compatible version that fully meets the minimum requirement. Version numbers in ODL follow semantic versioning, so a higher minor version (0.8.x vs 0.5.x) means it includes all features of older versions plus improvements.

If you still run into dependency-related errors during compilation, you can verify the Yang Tools version in the root pom.xml file of the controller repo. Look for a section like:

<dependency>
    <groupId>org.opendaylight.yangtools</groupId>
    <artifactId>yangtools-parent</artifactId>
    <version>0.8.0</version>
    <type>pom</type>
    <scope>import</scope>
</dependency>

This confirms the version is correctly set to a valid, compliant release.

3. Step-by-Step Compilation Command #

Once you're in the root controller directory, run these commands to compile (skipping tests can save time for initial builds):

# Clean previous build artifacts
mvn clean

# Compile and install the project
mvn install -DskipTests

If you encounter specific errors during the build, feel free to share the error logs for more targeted help!
