Is there a way to pass all properties from a property-file as JVM params?

We can pass a single property through java CLI using -D argument:

java -Dkey=value ...

Is there a way to pass all properties from a property file in that way?

Something like:

java -Dprop.file=myproperties.properties ...

There is no such option for java cli.

But this task can be achieved from command line with simple ant's build.xml using loadproperties and syspropertyset.

In your code with 

new Properties().load(...)

of course, but from command line the doc talks only about key=val

Be aware that there are some keys (eg. java.library.path) that must be set before your program runs and reseting in your code will have no effect.

You can if you add

System.getProperties().load(new FileInputStream(System.getProperty("prop.file")));
