When I download a JDK via the plugin "Eclipse Temurin installer" to a node which has Linux Alpine as OS, I get an error when accessing the JDK that it cannot be found.
This is because the downloaded JDK is based on GNU as the standard C library (gclib). Under Alpine, however, MUSL is used as the standard C library.
Therefore the JDK for Alpine Linux must be downloaded from Eclipse-Temurin.
Unfortunately, the plugin does not differentiate between Linux and Alpine Linux.
In the appendix you will find my adaptations for the support of Alpine Linux. I will also write down the relevant adaptations directly here.
/** * Supported platform */ public enum Platform { LINUX("linux"), ALPINE_LINUX("alpine-linux"), WINDOWS("windows"), MACOS("mac"), SOLARIS("solaris"), AIX("aix"); public static Platform current() throws DetectionFailedException { String arch = System.getProperty("os.name").toLowerCase(Locale.ENGLISH); if (arch.contains("linux")) { try { if (isLinuxAlpineDistro()) { return ALPINE_LINUX; } } catch (IOException e) { throw new DetectionFailedException(Messages.AdoptOpenJDKInstaller_Platform_unknownPlatform(arch)); } return LINUX; } if (arch.contains("windows")) return WINDOWS; if (arch.contains("sun") || arch.contains("solaris")) return SOLARIS; if (arch.contains("mac")) return MACOS; if (arch.contains("aix")) return AIX; throw new DetectionFailedException(Messages.AdoptOpenJDKInstaller_Platform_unknownPlatform(arch)); } private static boolean isLinuxAlpineDistro() throws IOException { final File releaseFile = new File("/etc/os-release"); if (releaseFile.exists()) { try (final Stream<String> lines = Files.lines(releaseFile.toPath(), Charset.defaultCharset())) { return lines.anyMatch("id=alpine"::equalsIgnoreCase); } } return false; }
