Updates swift-java project README (#411)

* Updates project README.md to clarify its current status, make the language around self-publication of supporting libraries more accessible, and remove the construction emoji that previously appeared.

@@ -5,16 +5,32 @@ This repository contains two approaches to Swift/Java interoperability.
 - Swift library (`SwiftJava`) and bindings generator that allows a Swift program to make use of Java libraries by wrapping Java classes in corresponding Swift types, allowing Swift to directly call any wrapped Java API.
 - The `swift-java` tool which offers automated ways to import or "extract" bindings to sources or libraries in either language. The results are bindings for Swift or Java.

+### Required JDK versions
+
+Note that this project consists of multiple modules which currently have different Swift and Java runtime requirements.
+
+You'll need to install the necessary JDK version locally. On macOS for example, you can install the JDK with [homebrew](https://brew.sh) using:
+
+```bash
+$ brew install openjdk
+# and create a symlink into /Library/Java/JavaVirtualMachines
+$ sudo ln -sfn /opt/homebrew/opt/openjdk/libexec/openjdk.jdk /Library/Java/JavaVirtualMachines/openjdk.jdk
 
-**:construction: This project is in early development, please keep this in mind as you try out the project and do provide feedback about any issues you encounter. :construction:** 
+# or if you have a distribution as cask it will be installed into /Library/Java/JavaVirtualMachines
+$ brew install --cask corretto
+```
 
-There is no guarantee about API stability of this package, neither in the Java or Swift parts, until the project releases a stable 1.0 release; APIs may change without prior notice.
+Alternatively, you can use a JDK manager like [sdkman](https://sdkman.io/install/) and set your `JAVA_HOME` environment variable:
+
+```bash
+$ export JAVA_HOME="$(sdk home java current)"
+```

+## Self-publish supporting Java libraries
 
-While we work out how to provide the necessary support libraries for the Java side of Java code generated by `swift-java jextract`,
-you will currently need to publish them locally and depend on them this way;
+Swift-java relies on supporting libraries that are under active development and not yet published to Maven Central. To use the project, you'll need to self-publish these libraries locally so your Java project can depend on them.
 
 To publish the libraries to your local maven repository (`$HOME/.m2`), you can run:

 ## SwiftJava macros
 
 SwiftJava is a Swift library offering macros which simplify writing JNI code "by hand" but also calling Java code from Swift.
