但maven不包含basic-util-1.0.1-SNAPSHOT 所以我将其编辑为

    <dependency>
        <groupId>org.imsglobal</groupId>
        <artifactId>basiclti-util</artifactId>
        <version>1.1.1</version>
    </dependency>

但它给了我这个错误

我该如何解决这个问题？

修改

我尝试过basiclti-util-1.0.0，但它给出了这个错误

Answer 1

使用

<dependency>
    <groupId>org.imsglobal</groupId>
    <artifactId>basiclti-util</artifactId>
    <version>1.0.0</version>
</dependency>

版本1.0.0包含basiclti包。版本1.1.1删除了basiclti包

Answer 2

lti-example-java已过时，并使用了basiclti-util-java的旧分支（其中包结构与1.0.0或1.0.1不兼容）。

它已更新，现在应该正常工作。

maven无法找到依赖basiclti-util
