Kotlin API
添加依赖
参考此处来配置您的 Maven;在 settings.xml 中设置您的 GitHub 账户和 Token。
Maven
在您项目的 pom.xml 中,按如下配置 Maven 仓库:
<repositories>
<repository>
<id>github</id>
<url>https://maven.pkg.github.com/kcl-lang/*</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
</repository>
</repositories>
通过这种方式,您将能够导入上述依赖以使用 Kotlin SDK。
<dependency>
<groupId>com.kcl</groupId>
<artifactId>kcl-lib-kotlin</artifactId>
<version>0.10.7-SNAPSHOT</version>
</dependency>
