Json webtoken 依赖项将不会在 pom.xml 中解析

Question

我目前正在开发一个 Spring 项目，这是我的新手，并且不知道为什么我从 maven 存储库获得的这种依赖性现在会自行解决。我尝试同时使用分离的依赖项（jjwt-api，等等）和粘贴在我下面的 pom.xml 中的依赖项，但它不会解析。如果有人能帮我解决这个问题，我将不胜感激。

Spring v2.6.4 Java JDK 17 错误消息：未找到依赖项 'com.auth0:java-jwt:3.18.3'

Answer 1

MvnRepository page says, it's in the central repo, and the central repo link to the pom.xml of the dependency also works: https://repo1.maven.org/maven2/com/auth0/java-jwt/3.18.3/java-jwt-3.18.3.pom

那你有没有试过离线解决一次？解析失败也会缓存在您的本地 Maven 存储库中，因此您可能需要清理它。你可以尝试使用

mvn dependency:get -Dartifact=com.auth0:java-jwt:3.18.3

或者您手动清除缓存的“缺失”依赖项：转到您本地的 Maven 存储库（通常在 ~/.m2/repository），下降到 com/auth0/java-jwt 并删除里面的文件夹 3.18.3，然后运行你的 maven 再次构建。

我刚刚重新加载了 pom.xml 文件，它起作用了。

Json webtoken 依赖项将不会在 pom.xml 中解析
