我剛剛設置了我的第一個項目，使用apache作爲依賴項管理器的ivy。它工作得很好！但我有一件事我無法克服。由於我有幾個使用slf4j的依賴關係，因此與版本不匹配有衝突。所以我在ivy.xml中定義了一個衝突標籤來強制某個版本（本例中爲1.5.6）。使用eclipse插件運行常春藤解決方案IvyIDE可以正常工作。但是用我的Ant構建文件來構建我的應用程序時，我得到一個XML語法錯誤：Apache Ant +常春藤語法錯誤

錯誤發生在螞蟻目標'resolve'中。常春藤似乎被加載的設置文件也按預期使用。但正如已經提到的，我得到了這個語法錯誤。
有沒有人看過這個之前，可以給我一個提示？
問候，
塞巴斯蒂安
謝謝。我也遇到過這個。將衝突標記移動到依賴關係塊的末尾工作。謝謝。 –
