使用Java 9在Linux上创建模块化jar时出现java.nio.file.NoSuchFileException

Question

I have been trying to create a modular JAR in Java 9 running on Linux. Every time I run the command: jar --create --file=mlib/math.util@1.0.jar --module-version 1.0 -C mods/math.util . I get the following exception

java.nio.file.NoSuchFileException: /tmp/math.util@1.0.jar2983688172420627243.jar -> mlib/math.util@1.0.jar
        at sun.nio.fs.UnixException.translateToIOException(java.base@9-ea/UnixException.java:92)

        at sun.tools.jar.Main.main(jdk.jartool@9-ea/Main.java:1769)

But the same command worked fine on Java 9 running on Windows. And I was able to successfully create the JAR.

I have been trying as root user on Linux.

can someone help me with solving this issue?

我发现在运行JAR命令之前并没有创建mlib目录，因此没有例外。
