Graal: native-image -H:Name is ignored

[apetrelli]

Hello
I am using GraalVM 1.0.0-rc7. No matter what parameter I send for -H:Name, it gets constantly ignored, getting the name from the jar file instead.
You can see the project here:
https://github.com/apetrelli/scafa/tree/master/scafa-headless

The command line is:
/home/anpetrel/javadev/libs/graalvm-ce/bin/native-image --verbose -cp /home/anpetrel/.m2/repository-ispcasa/com/github/apetrelli/scafa/scafa-server/1.0.0-SNAPSHOT/scafa-server-1.0.0-SNAPSHOT.jar:/home/anpetrel/.m2/repository-ispcasa/jcifs/jcifs/1.3.17/jcifs-1.3.17.jar:/home/anpetrel/.m2/repository-ispcasa/org/ini4j/ini4j/0.5.4/ini4j-0.5.4.jar:/home/anpetrel/.m2/repository-ispcasa/commons-io/commons-io/2.4/commons-io-2.4.jar -H:ReflectionConfigurationFiles=src/etc/graal.json -H:EnableURLProtocols=http -H:Path=/home/anpetrel/git/scafa/scafa-headless/target/deb/usr/bin -H:Name="scafa-headless" --rerun-class-initialization-at-runtime=jcifs.ntlmssp.Type3Message --no-server -jar /home/anpetrel/git/scafa/scafa-headless/target/scafa-headless-1.0.0-SNAPSHOT-graalvm.jar

What I see at the start is:

Even if I remove the " around the name, -H:Name gets ignored anyway.

@apetrelli please put -H:Name="scafa-headless" after -jar /home/anpetrel/git/scafa/scafa-headless/target/scafa-headless-1.0.0-SNAPSHOT-graalvm.jar.

[apetrelli]

Ok thank you, this worked!
But anyway it probably needs documentation if it works this way.

Some more details:

Using -jar instructs native-image to name the image after the jar-file name. (Which often makes sense). If you want to override that behavior you have to place -H:Name="my-native-image-exe-name" after the -jar option. That's a general principle of native-image option handling. To provide defaults/fallbacks put options before other affecting options. To override decided options put them after the other affecting options. This is the same principle that is used by most compiler-drivers. See e.g. https://gcc.gnu.org/onlinedocs/gcc/Optimize-Options.html#Optimize-Options

If you use multiple -O options, with or without level numbers, the last such option is the one that is effective.

OK this way I demonstrated that I am a newbie in native compilation. Thank you and have a nice day!

@olpaw this issue caught me out as well! I think a line in the docs is justified for this.

https://www.graalvm.org/reference-manual/native-image/Options

The reference manual currently doesn't state anything about argument/option ordering, it simply states

native-image [options] -jar jarfile

Which would make one think that any -H:Name=myname option would need to go before the -jar argument, not after.

Thanks 🙂

@alzadude we have that under https://www.graalvm.org/reference-manual/native-image/Configuration/#order-of-arguments-evaluation. Maybe that should be linked to also from https://www.graalvm.org/reference-manual/native-image/Options
@olyagpl please add something like

The arguments passed to native-image are evaluated left-to-right. For more info see.

@olpaw, done!
