[graalvm-users] Error compiling SL against Java 9

[Peter Burka]

I’m trying to get started with Truffle, so I began by trying to build the
Simple Language example following the instructions at
https://urldefense.proofpoint.com/v2/url?u=http-3A__www.graalvm.org_docs_graalvm-2Das-2Da-2Dplatform_implement-2Dlanguage_&d=DwIFaQ&c=RoP1YumCXCgaWHvlZYR8PZh8Bv7qIrMUB65eapI_JnE&r=CUkXBxBNT_D5N6HMJ5T9Z6rmvNKYsqupcbk72K0lcoQ&m=9VGNy7bfGnOyG8vk9X_ZjnxT1Id2Oz7Iqorhn56mYeg&s=_9wkbk0vHTV9o_eRbRdSDoKYX9V1jpxj8aC6zuAWYJ8&e=



***
Note! I skipped step 1 (“Ensure you set up GraalVM before you begin”)
because I’m using a Java 9 SDK, and it’s my understanding that this
includes Graal. This could be the source of all my problems below. If so,
perhaps the https://urldefense.proofpoint.com/v2/url?u=http-3A__www.graalvm.org_docs_getting-2Dstarted_&d=DwIFaQ&c=RoP1YumCXCgaWHvlZYR8PZh8Bv7qIrMUB65eapI_JnE&r=CUkXBxBNT_D5N6HMJ5T9Z6rmvNKYsqupcbk72K0lcoQ&m=9VGNy7bfGnOyG8vk9X_ZjnxT1Id2Oz7Iqorhn56mYeg&s=Lh65NWvlvftk_K95mpmeNGAy8o-zfQlRMD9umbj56is&e= page should be
updated to mention Java 9.

I’m using Maven 3.3.9 and Java 9.0.4. I’m also behind a corporate firewall
and using a web proxy, but I don’t think that’s related.

When I run mvn package, I get the following compile errors:

Any chance this is a known issue?

If it’s related to using a standard Java 9 build, is there a solution for
building Simple Language against the SDK? I don’t want to require my
potential users to build a custom SDK.
