From: przemelek Date: Sun, 19 Aug 2018 22:09:52 +0000 (-0700) Subject: Changes to display JVM installations on macOS/OSX. X-Git-Tag: light-jdk8u181+2^2 X-Git-Url: https://source.dussan.org/?a=commitdiff_plain;h=917b108e69a2b91fa8e260a938523b88eb79959e;p=dcevm.git Changes to display JVM installations on macOS/OSX. Main change here is in Installer.java where scanDirectory was changed to work recursively, thanks to this we are able to find JVM on macOS which are in less predicable places ;-) on macOS JVM location will be for example /Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home, but scaning /Library/Java/JavaVirtualMachines/ without this recursive thing will not find JVM. Additionally changed text in MainWindow which suggests now that users should prefer alternate JVM over replace JVM, with short "explanation" why. --- diff --git a/installer/src/main/java/com/github/dcevm/installer/ConfigurationInfo.java b/installer/src/main/java/com/github/dcevm/installer/ConfigurationInfo.java index e8fa5390..1966bd9c 100644 --- a/installer/src/main/java/com/github/dcevm/installer/ConfigurationInfo.java +++ b/installer/src/main/java/com/github/dcevm/installer/ConfigurationInfo.java @@ -37,13 +37,19 @@ import java.util.regex.Pattern;
