We delete and recreate new user accounts as new trainees enter the organization, and the. Let me know if there are any other details I can provide. I'd like to help see this resolved, as there are people in the organization who are still clinging to the old, outdated, deprecated Google Plugin for Eclipse, and it seems the world is trying to move forward.
Again, I'm happy to help. Thank you for the detailed reporting. I have some ideas for diagnostics. I will give you an update in a couple hours. Random thought: your screenshot does not show the real Maven central, which is at search. Would it be possible to launch your Eclipse with eclipse -console and copy-and-paste the output here? After this, repeat the whole steps 1 to 7 again but with creating Maven App Engine Standard projects.
Is there a difference? Before you try all that, it might be worth trying a simple "jar tvf" on the file to see if that reports any problem. Here is the error log from eclipse for one instance where the file was again corrupt. This time, instead of 88kb, it was 73kb. I'm actually trying this with 7 different Windows machines and am getting varied results. Sometimes, if I delete the. On some machines, it worked on the first try. We are behind a proxy that caches files so that we don't download the same things over and over and consume massive bandwidth.
I just tried with my mobile hotspot on a machine. It worked successfully the second two times, but the first time, Eclipse hung while installing the "dynamic web module" that gets installed when you create a new App Engine Standard project.
I can't do too many more tests because the hotspot is really really slow. So it does look like something is sometimes corrupting the. Now what to do about that? There might be a point where we can detect this and redownload. I'm surprised maven itself doesn't check the SHA on download, but apparently it doesn't.
Possibly we could do this here:. However we're delegating to M2E to actually download artifacts. I wonder if there's something to report upstream to either M2E or Maven? Ooh, I'd forgotten about But I don't think it's related: involved importing Maven-based projects with m2e, whereas jamesmortensen is dealing with non-native native projects.
So the m2e ResourceChangeListener and auto builder won't be involved. One of our integration tests, DebugNativeAppEngineStandardProjectTest , does exactly what you're describing: it creates a new native project, and launches it in debug mode, and verifies that it receives a response. This test is run on Windows on every PR i. We have never seen failures due to corrupt artifacts like this. If this happens on every machine in your organization, then I place my bet on corrupted files in your proxy.
The javax. CT4E on the other hand will attempt to download from :. Please try downloading this second link. Assuming your browser is using the same proxy as M2Eclipse , I suspect you'll find this artifact is broken. I'm not sure what the "Default" setting does, but the "Fail" should report some kind of error. Sometimes files were good, and sometimes they weren't. I'll try the next part when I get ahold of another Windows computer, assuming the information from that test would still be useful to you.
I'll need to try again from one of the Windows computers used in training next time I get my hands on one. Will try to do both of these tests, including the M2Eclipse "Fail" setting, today or Monday.
Another update: I just had a trainee come to me with a Macbook Air with the same corrupt javax. Thus, this is not limited to Windows only. I downloaded a fresh copy and swapped out the file in the. Sorry it's taking so long on running the other tests. It's been a busy week but I'll work on getting you the other data you asked for. RE: comment. I ran through the steps to create a Google App Engine Standard project, but checking the checkbox to "Create as Maven project".
All nine times I created it, the javax-servlet-api This explains why our instructions to the trainees to create their first project as a Maven project, delete it, and then create a non-Maven Google App Engine Standard project resulted in success. The files do not get corrupted when creating a Google App Engine Standard project as a Maven project. Lastly, I ran the third part of the tests where I create a "Maven simple project" to check for a problem in the general environment.
I did this nine times. All nine times, there was no problem downloading the javax-servlet-api It was 94kb each and every time. I completely removed the. Again, it seems the problem is limited to only creating Google App Engine Standard projects without checking the Maven project checkbox!
I hope this information is helpful in debugging and fixing whatever is causing this problem. Let me know if there's any other details I can provide. It is behaving as if this setting actually checks the checksum and perhaps makes attempts at re-downloading the corrupted files? Is there a way to see if that's what's happening? If this was the default behavior, that would be awesome, as no files are corrupt using this setting after about 7 attempts.
