From 69d7ad808aa5e1c39f29610cefa619e2c4f57746 Mon Sep 17 00:00:00 2001 From: Foivos Zakkak Date: Wed, 5 Jan 2022 12:08:04 +0200 Subject: [PATCH] Unify instructions for both Mandrel and Oracle GraalVM Mandrel has now matured and provides builds for both Linux and Windows systems. Unifying the instructions makes the guide easier to follow and removes the implication that Mandrel cannot be used instead of Oracle GraalVM in some cases. This commit also removes the hint for using Java 11 (instead of Java 8). Java 8 is no longer supported and the community should be encouraged to start testing Java 17. --- .../main/asciidoc/building-native-image.adoc | 39 ++++--------------- 1 file changed, 8 insertions(+), 31 deletions(-) diff --git a/docs/src/main/asciidoc/building-native-image.adoc b/docs/src/main/asciidoc/building-native-image.adoc index d16cd839f5a9d..3de01b353b8b3 100644 --- a/docs/src/main/asciidoc/building-native-image.adoc +++ b/docs/src/main/asciidoc/building-native-image.adoc @@ -48,37 +48,15 @@ Building native executables directly on bare metal Linux or Windows is possible, with details available in the https://github.com/graalvm/mandrel/blob/default/README.md[Mandrel README] and https://github.com/graalvm/mandrel/releases[Mandrel releases]. -The prerequisites vary slightly depending on whether you are using Oracle GraalVM CE/EE or Mandrel. +== Prerequisites -[IMPORTANT] -.Install the Java 11 version of GraalVM -==== -While Oracle GraalVM is available for both Java 8 and Java 11 (Mandrel only supports Java 11), Quarkus only works with the Java 11 version. -If you use the Oracle distribution, make sure to install the Java 11 version. -==== - -== Prerequisites for Mandrel - -To complete this guide using Mandrel, you need: - -* less than 15 minutes -* an IDE -* JDK 11 installed with `JAVA_HOME` configured appropriately -* A working container runtime (Docker, podman) -* The code of the application developed in the xref:getting-started.adoc[Getting Started Guide]. - -Skip to <<#container-runtime,this section>> to continue with the guide for Mandrel, -and follow the Mandrel-specific instructions in that section. - -== Prerequisites for Oracle GraalVM CE/EE - -To complete this guide, you need: +To complete this guide using Oracle GraalVM CE/EE, you need: * less than 15 minutes * an IDE * JDK 11 installed with `JAVA_HOME` configured appropriately * A xref:configuring-c-development[working C development environment] -* GraalVM version {graalvm-version} (be sure to install the Java 11 support) installed and xref:configuring-graalvm[configured appropriately] +* Mandrel or Oracle GraalVM CE/EE version {graalvm-version} installed and xref:configuring-graalvm[configured appropriately] * A working container runtime (Docker, podman) * The code of the application developed in the xref:getting-started.adoc[Getting Started Guide]. @@ -116,10 +94,9 @@ If you cannot install GraalVM, you can use a multi-stage Docker build to run Mav Version {graalvm-version} is required.
