JAX-RS Rest services stopped deploying on Eclipse

Question

I've been developing a Jersey JAX-RS application on Glassfish 4.1.1 using Eclipse for about a year now. Earlier today, I was making some normal changes to some of the classes, but Eclipse was not updating the classes when I would try and do a build. I searched here on Stack Overflow, and found this answer.

So I did the following steps:

1. Project > Clean on the project you're working on.
2. Project > Build Automatically - turned on so the code rebuilds in your workspace on saved changes.
3. Window > Preferences and make sure your Installed JRE's and Compilers are matching Java versions

My installed jre is jdk1.8.0_73 and my compiler compliance level is 1.8

Now when I make a change to a Java file, the server tab below will still not show

[Started, Republish]

like it should but stays at

[Started, Synchronized].

It gets worse. Now when I try and hit the rest services using POSTMAN and queries that I've used a million times it returns a 404 saying the requested resource is not available.

So basically none of the REST services are starting properly for some reason.

If I hit the index.html for my application it gets served up fine, but when AngularJS tries to load stuff from the REST backend, it gets fed the 404 error.

I've haven't made any changes to Eclipse/Glassfish, as it was working perfectly yesterday. This is totally stopping development. Anybody know what might have gone wrong? It is extremely mind-explodingly annoying.

I'm no expert in Eclipse or Glassfish or jersey, so please go easy on me :)

Here are the build logs for when I start the server, maybe somebody can notice whats going on....

Answer 1

It looks like this error was caused by the project not building properly. Upon inspection of the buildpath, it seemed two jar files were mysteriously missing! They were:

jersey-media-multipart-2.21.1.jar
mimepull-1.9.3.jar

I have no idea how the jar files were deleted from the /lib directory of the glassfish server, maybe I shouldn't have drunk that extra bottle of whiskey. Once they were added back in, everything suddenly worked hunky dory. A little baffled by the error - i would have thought it would give a compile error if the jar wasn't available. Anyhow, 5 days lost due to another annoying error.
