Question

我正在尝试使用Netbeans构建的两个项目在Windows 10中创建一个多版本jar。项目是相同的，唯一的区别是一个有jdk8属性＆gt;源/库和另一个有jdk9。它们都有一个 com.jdojo.mrjar 包，在它下面都有一个TimeUtil类

public class TimeUtil {
    public TimeUtil() {
        System.out.println("Creating JDK 8 version of TimeUtil...");
    }
    public LocalDate getLocalDate(Instant now){
        return now.atZone(ZoneId.systemDefault()).toLocalDate();
    }
}

一个简单的主类叫它

public class Main {
    public static void main (String[] args) {
        System.out.println("Inside JDK 8 version of Main.main([])...");
        TimeUtil t = new TimeUtil();
        LocalDate ld = t.getLocalDate(Instant.now());
        System.out.println("Local Date: "+ld);
    }
}

jdk9版本还有一个module-info.java：

module com.jdojo.mrjar {
    exports com.jdojo.mrjar;
}

他们都编译并正常运行，但是当我尝试命令时 jar --create --file mrjars \ com.jdojo.mrjar.jar -C com.jdojo.mrjar.jdk8 \ build \ classes。 --release 9 -C com.jdojo.mrjar.jdk9 \ build \ classes。我有以下错误：

Warning: entry META-INF/versions/9/.netbeans_automatic_build contains a class that
is identical to an entry already in the jar
Warning: entry META-INF/versions/9/.netbeans_update_resources contains a class that
is identical to an entry already in the jar

截至How to create multi-release jar and filtering input content?，如果我尝试建议的解决方案，我有

$(find : no such file or directory
-name : no such file or directory
*.class) : no such file or directory

所以我只是从文件夹中删除了.netbeans_automatic_build和.netbeans_update_resources文件，因为它们似乎是问题的原因，如果我现在尝试命令我有不同的错误

java.nio.file.NoSuchFileException: C:\Users\Talon\AppData\Local\Temp\com.jdojo.mrjar.jar12504656669179695067.jar -> mrjars\com.jdojo.mrjar.jar

我已经检查了该文件夹，并且com.jdojo.mrjar.jar12504656669179695067.jar不存在，问题是为什么它应该是？
