java - 在Windows和Linux上构建的单个JAR有何不同？

我正在构建一个jar文件以在Hadoop集群上运行它。当我在Windows平台上构建jar并将其复制到Hadoop机器时，它可以正常工作，但是当我在Linux机器上构建jar时。它给了我以下错误:

Exception in thread "main" java.io.FileNotFoundException: /tmp/hadoop-unjar7077828764688507370/META-INF/maven/com.google.guava (Is a directory)
    at java.io.FileOutputStream.open0(Native Method)

    at org.apache.hadoop.util.RunJar.run(RunJar.java:209)
    at org.apache.hadoop.util.RunJar.main(RunJar.java:136)

pom.xml的提取如下:

让我知道您是否需要其他文件。

最佳答案

您可以尝试添加 Guava 依赖项:

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