proguard: Can't read [C:\Program Files\AdoptOpenJDK\jdk-11.0.6.10-hotspot\lib\rt.jar]

Question

I am building a desktop application. I am using ProGuard with the following config:

@proguard_jmods.cfg
#-dontshrink
-dontoptimize
#-dontobfuscate


-repackageclasses ''
-renamesourcefileattribute SourceFile
-keepattributes *Annotation*,Signature,Annotation,InnerClasses,EnclosingMethod,SourceFile,LineNumberTable

# Keep - Applications. Keep all application classes, along with their 'main' methods.
-keepclasseswithmembers public class * {
    public static void main(java.lang.String[]);
}

-keep interface *
-keepnames class ** implements com.xxx.xx.utils.ISerialisable
-keepclassmembers class ** implements com.xxx.xx.utils.ISerialisable {
  <fields>;
  }

-keep,allowshrinking class ** extends com.xxx.xx.utils.ISerialisable

# Keep - Applications. Keep all application classes, along with their 'main' methods.
-keepclasseswithmembers public class * {
    public static void main(java.lang.String[]);
}

# Also keep - Enumerations. Keep the special static methods that are required in
# enumeration classes.
-keepclassmembers enum  * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

# Also keep - Database drivers. Keep all implementations of java.sql.Driver.
-keep class * extends java.sql.Driver

# Keep - Native method names. Keep all native class/method names.
-keepclasseswithmembers,includedescriptorclasses,allowshrinking class * {
    native <methods>;
}

where proguard_jmods.cfg contains the following:

-libraryjars 'C:\Program Files\AdoptOpenJDK\jdk-11.0.6.10-hotspot\jmods\java.base.jmod'
-libraryjars 'C:\Program Files\AdoptOpenJDK\jdk-11.0.6.10-hotspot\jmods\java.desktop.jmod'
-libraryjars 'C:\Program Files\AdoptOpenJDK\jdk-11.0.6.10-hotspot\jmods\java.xml.jmod'

When Run As>Maven Install, I get the following exception thrown:

[proguard] java.io.IOException: Can't read [C:\Program Files\AdoptOpenJDK\jdk-11.0.6.10-hotspot\lib\rt.jar] (No such file or directory: C:\Program Files\AdoptOpenJDK\jdk-11.0.6.10-hotspot\lib\rt.jar)

I check the path for that file, and I don't have it. Any idea how to fix this please? Thank you!
