為什么加特林項目不適用於 maven？

Question

我從加特林開始，我有一個 maven 的項目，帶有最新版本的加特林和 scala，我已經檢查了 ide 中的所有參數化，我已經更改了版本，但沒有任何效果

這里顯示我的 pom.xml

我該如何解決這個問題？

我希望你的幫助，請

Answer 1

您的配置是正確的，因此如果在類路徑中找不到 Gatling 的類，則意味着本地 maven 緩存中應該包含它們的 jar 已損壞。

這可能發生在較差的網絡上，遺憾的是 maven 沒有驗證校驗和以確保下載沒有損壞。

從本地 maven 緩存中刪除io.gatling:gatling-core （默認為~/.m2 。
