Windows和Linux上的單個JAR如何構建？

我正在構建一個jar文件以在Hadoop集羣上運行它。當我在Windows平臺上構建jar並將其複製到Hadoop機器時，它工作正常，但是當我在Linux機器上構建jar時。它給了我下面的錯誤：Windows和Linux上的單個JAR如何構建？

Exception in thread "main" java.io.FileNotFoundException: /tmp/hadoop-unjar7077828764688507370/META-INF/maven/com.google.guava (Is a directory)

讓我知道如果你需要的任何其他文件。

比較兩個文件，可以手動或使用工具，如「無法比擬」。你是否在同一臺計算機上運行其中的一個文件？ – Marged

你可以嘗試添加番石榴依賴性：

<dependency> 
    <groupId>com.google.guava</groupId> 
    <artifactId>guava</artifactId> 
    <version>21.0</version> 
</dependency>

我試過這個，它確實工作，但是，一個新的「org.apache.commons」（是一個目錄）出現，這次添加依賴不起作用。我認爲這個問題有根本原因，爲此，我需要了解在不同平臺上構建jar的差異。 –
