查詢原因
在網上根據這個報錯搜尋了一番,各種答案都和我這個好像沒有關係,而且他們的解答好像都是複製了,都沒說明原因
那就只能自己想辦法解決,報錯解釋:不支援具有相同組名的多個文件。發現以下重複組。default
完全沒有頭緒,default ,然後mvn pakcage -X 打包查詢也是相同的錯誤,沒有更詳細的原因,
問題點
根據報錯提供的 documentationPluginsBootstrapper 和 DefaultLifecycleProcessor.doStart(DefaultLifecycleProcessor.java:185) 和 報錯列印
找到 DefaultLifecycleProcessor 中丟擲異常的地方,找到
DocumentationPluginsBootstrapper.start() 方法報錯,debug ,找出更深層的報錯 在 DocumentationPluginsManager.documentationPlugins()
最後發現是有兩個 Swagger 文件的配置類,然後去掉其中一個就恢復正常了
