![]() ![]() (Tip: You can use the same you use in the iTunes Store.) After logging in, type “java developer package” in the search field (see screenshot). Fortunately, it’s free but you still need to register it. You’ll need an AppleID to download the JDK. ![]() The JDK for Mac OS X comes as “Java Developer Package”. Eclipse doesn’t ship with the Java source code though. That’s why you don’t need to install a JDK to create Java programs with Eclipse. Remark: Eclipse comes with its own Java compiler. The JDK includes the JRE, and also comes with Java’s source code. JDK: The “Java Development Kit” is required when you want to compile Java programs. You cannot, however, compile Java programs with just the JRE. JRE: The “Java Runtime Environment” is necessary to run Java application.When working with Java, you need to distinguish two Java software package types: We’re currently running ‘openjdk version “1.8.0_212”’.That’s the “Java version” you need to know. I’ve also read that Java 10 and Java 11 are smart enough to figure out they’re inside docker and behave…but we haven’t tried a recent Java with the app. I can find the image file, but there’s no Dockerfile there. If I’m using Docker Desktop for Mac, where’s the relevant Dockerfile? I should specify the memory for the jvm…but both web pages reference a Dockerfile. I understand that the JDK that I have installed cannot know how much memory it really should be having, and that I need to specify that the MaxRAMFraction of 4 shouldn’t be used for the docker instance. ![]() The image had 2GB of Ram, and I’ve bumped it up to 4GB…but that hasn’t changed the crashes much. One of the issues I’m dealing with are seemingly random ‘Out Of Memory’ incidents. Docker Desktop might have ben installed from homebrew, FWIW. I inherited an image that has Jenkins installed on it, and the android SDK more-or-less installed. These versions have a longer support timeframe. It is suitable for running all workloads. It is an enterprise-grade VM designed for low memory footprint and fast start-up and is used in IBM’s JDK. I’m running Docker Desktop for Mac (2.1.0.5 (40693)). Eclipse OpenJ9is the VM from the Eclipse community. I’m trying to run a build server for Android on a Mac mini (Mac OS 10.14.6). ![]()
