Some things don't work due to ongoing development.

Downloads

You'll need a JDK... You can get one here: Oracle JDK's. Windows is [x86 (32 bit) and, x64 (64 bit) @see: /ca/tecreations/Apps/Notes.php], anything else, you should know what to do or who to contact. Anything newer than version 17 should work. I compile to version 17, but you can change that. Minimum is Java 9/11 for Process.pid() and I think there were some crypto changes, so 11, but I forget easily.

You'll probably want an IDE. I'm working on editor, but it's slow and careful work, yo. I use NetBeans and a Java Ant Project with Existing Classes and package to .jar using ca.tecreations.apps.deploy.Deploy, but you can use any text editor and Command Promt, or terminal, or jethro.jar to launch. Compiling is automatic via ca...apps...JavaCompiler, you can press your IDE manufacturer to not show compiled, or old version files, if you want, OR??? Code it yourself. All my code is here, I can work on any part at any time. I'd rather earn my own money?

You can do a Maven/Ant style project by using DependencyViewer.

I try to test each piece and branch of execution possible, as I develop, so some things may not work due to dependency code changing, or my not having been able to get back to it yet (ie, FileTool).

At any time, you should be able to delete the TEC_VERSION.jar, TEC_VERSION_jars.jar and <user.home>/tecreations/, unless you have running applications, and/or, open files (active locks). Sometimes applications run aberrantly, so may need to be shutdown via TaskManager or similar.

Download TEC_VERSION.jar : jethro.jar
Double Click TEC_VERSION .jar, currently "jethro.jar".

Caution...:

If you haven't configured your PROJECTS_HOME, the default compilation directory root -- then -- the software ***SHOULD*** prompt you to dedicate a directory for projects.
ca.tecreations.ProjectPath.PROJECTS_HOME == ProjectPath.getTecPropsPath() + "ProjectPath.properties" ---> "PROJECTS_HOME" :::-> $value
JavaCompiler does not permit compilable paths without a PROJECT_DIR, so, for example, : 'PROJECTS_HOME\test2.java' WILL NOT WORK and will crash the JavaCompiler.
You must specify something like 'PROJECTS_HOME\test\test2.java', where PROJECT_DIR == "test", and that should work.
If the JavaCompiler encounters an exception, it will cause compilation to stop, no if's, and's, or but's about it. You can change it; I like it this way.

JavaCompiler will attempt to start or restart.
If missing, your security configuration for localhost will be created.
Finally, Launcher will launch in a few seconds.
For now I need the output, so I'll add System.exit(0) to Validate1.java, again, soon.
Happy Coding!

Still to do...

Have to test with making newer /jars/ -- JavaMail API
perform HelloWorld output COMPARISON? test.

And then launch what you want, from any jar, classpath, or command line.

Yeah, it needs work -- especially in the library apps. Commandline input isn't coded yet, but my Spring Security project works for now, and that's all I need for experimenting.?

I'm sorry, I'm only 1 guy. I guess it could be made a private repo, with multiuser access for editing and approving changes. That would take some effort.
