您需要查找您的父pom並檢查您在dependencyManagement部分使用的庫依賴關係。由於你的pom上很多庫上沒有版本標籤。我建議你在你的項目中運行一個依賴樹，你可能使用了依賴於對方的不同版本的庫。 –

我已經包含了我正在使用的庫的版本號，但仍然收到相同的錯誤。我從來沒有在maven中使用過parent和dependencyManagement標籤，你可以通過代碼展示它在這種情況下的使用方式嗎？ –

要解決此錯誤，您需要管理dependencyManagement部分中衝突工件的版本。

例如：要解決這一問題的edu.illinois.cs.cogcomp:illinois-core-utilities您需要在您的dependencyManagement部分像

<dependency> 
    <groupId>edu.illinois.cs.cogcomp</groupId> 
    <artifactId>illinois-core-utilities</artifactId> 
    <version>3.0.72</version> 
</dependency>

的條目。

pom文件中已經有一個dependencyManagement tage。請看看我已經更新了這個問題。你的建議沒有解決，你能提出其他建議嗎？ –

你是什麼意思：「沒有工作」？您是否真的將所有相互矛盾的依賴項（edu.illinois.cs.cogcomp：illinois-core-utilities，edu.illinois.cs.cogcomp：LBJava，...）添加到您的dependencyManagement作爲我向您展示的條目？然後請編輯問題並顯示完整的pom和你得到的錯誤。 –

非常感謝！你的解決方案工作 –
