I use ant. And git hooks (sometimes).
I don't have many dependencies .. pdfbox, some commons http stuff, mail, jax, jdbc, gson. Dev build builds local expanded directory deployment, touch web.xml to reload the app. Prod build builds the jar/war. DB2DOM provides persistence, vws, security, and other doodads. I've proven the example in a few dozen scenarios including MP3 audio encoding and video streaming from an underground mine (4000+ feet). I run tomcat with DB2DOM in dev .. access and modify css, JS, and Java in a web browser (syntax highlighting is the extent of my coding assistance, DB2DOM makes things pretty routine so I don't need to know many libraries, and the compiler gives me detailed information). I'm doing jdb remote debugging by command line as needed. I have build, buildProd, deployProd scripts that don't completely automate to production server (but could very simply, I just don't so I have some human intervention). The entire solution including DB2DOM, but not the application code is around 250K including scripts of my code for build/deploy. Hey, at least I don't have property files. My properties are stored in the DB. It's pretty simple, lightweight, and fun to save a CSS/JS file to the server and immediately test, and to have lowest common denominator scripts for dev/ops that tend to be easy to troubleshoot (lots of older school script experts out there). The entire thing including a web browser runs on a 3B+, even. It's a little slow, but in terms of what is usually required to support an enterprise development environment, DB2DOM does for software what the CNC machine did for manufacturing (spoiler alert, CNC didn't take over all manufacturing, but did force multiply design capabilities by being able to rough-out 90% of the work for a toolmaker). I create a table, then use a simple API to CRUD tables: Data.create(connection, "Table", populatedHash, catalog); Data.findHash(connection, "Table", "sqlLookup", paramsCollection, catalog); I have created a data navigator that allows me to populate test data through a web browser that keeps all the ID's in synch. It handles blobs, images, audio, boolean, string, and date. So, I have a graph crud'er that is fully functional for tables that I just created (and tables I haven't created, yet). This has been very valuable for new applications, to create test data immediately that has relational integrity. DB2DOM reads db metadata and maintains an in-memory model to drive automation of coding tasks and produce other metadata/compilable code that can be copy/pasted. I once used DB2DOM to auto-generate a complete set of entity beans for an entire schema. It was not a high value proposition, just a challenge issued to me and the challenge was accepted. I also used DB2DOM to create the unicorn of information systems engineering .. the generic entity bean. But it was redundant. DB2DOM did everything better and more lightweight. But it was a nice proof of concept. I built this all myself without some super genius middle manager poking me in the back all the time. Go figure.
