Graal: [native-image] can't compile on docker

Created on 21 Apr 2018  ·  3Comments  ·  Source: oracle/graal

I tried to build simple code with native-image on docker + graalvm-ce-1.0.0-rc1, but native-image throwed NullpinterException.
And same program is sucess on MacOS + graalvm-ee-1.0.0-rc1.
Haven't yet native-image support Docker? Or should I need some configuration to Dockerfile?

[root@c74702bf3869 /]# javac HelloWorld.java
[root@c74702bf3869 /]# java HelloWorld 
Hello, World
[root@c74702bf3869 /]#　native-image --verbose HelloWorld

@koduki this a bug in the classpath handling of image building when the classpath contains the root directory (/). I'm going to fix this ASAP. In the meantime as a workaround I suggest image building in a subdirectory:

[root@f00d70fe6273 /]# mkdir foo
[root@f00d70fe6273 /]# cd foo 
[root@f00d70fe6273 foo]# echo "public class HelloWorld { public static void main(String[] args) { System.out.println(\"Hello World\"); } }" > HelloWorld.java
[root@f00d70fe6273 foo]# javac HelloWorld.java
[root@f00d70fe6273 foo]# java HelloWorld
Hello World
[root@f00d70fe6273 foo]# native-image HelloWorld

Thank you for your information.
I can build & run on a sub-directory.

BTW, I have fixed this on master: https://github.com/oracle/graal/commit/f53341bdb1db374b0f2f47e4f323e31430562a96
So if you really want to build with / on the classpath it will no more be a problem in future releases (but I still recommend not to do so).
