Build Failed

[ankrit...@gmail.com]

Hi,

I am trying to build using ant, after doing some changes in code.

How do I identify the cause of the failure?

I made changes in some classes related to SpeechRecognizer component, but I cannot see any build error lines related to the same files in the whole build process log.

How to understand this log and identify the cause of build failure?

Following is the output of ant command:

$ ant

Hi there,

The key is to find the first error or exception and take it from there. In your case, it seems to be at:

[java] java.lang.IllegalArgumentException: Unable to parse file - cannot locate beginning of $JSON section

This is something that has been discussed in this forum before, so next step is to do a search.

Hi Jose,

I looked at it and found that I faced this issue earlier too, to which Evan suggested merging PR  https://github.com/mit-cml/appinventor-sources/pull/1556.

This PR has already been merged to the master. And, I just updated my master too. 

Is there any other possible solution?

[ankrit...@gmail.com]

Hi,

I just wanted to confirm if this error is only with my build system or others are also facing the same issue?

Should I re-clone my forked repo(since it was working well, last time I pushed something in it)? Please suggest to me.

Thanks.

[Jose Dominguez]

Hi Ankriti,

this seems to be an issue on Windows only, so I guess not that many
people use that platform for development. I personally do not have
access to a [virtual] machine with Windows at the moment.

You can try and clone again, or you could try using a virtual machine,
if you'd rather do that.
There is a pull request for a Vagrant environment that you can test if
you want too: https://github.com/mit-cml/appinventor-sources/pull/1540
There also a very possibly outdated Docker file for AI too:
https://github.com/josmas/appinventor-env-docker

None of those answer your question directly, though.

cheers,
José

[Evan W. Patton]

Does it fail even when you checkout master and pull?

Hi Jose, I think I should switch to linux then. It looks more reliable for development purposes.

Hi Evan, I stashed all changes, switched to master, updated and built it. It was successful.

Another thing that I did was I cloned my forked repo and built my speech-recognizer branch with the last commit. It builds fine. Then I copy-pasted modified files since the last commit on my branch and then build failed. Are there some issues with the current code changes I did, that is causing build failure? Though most of the changes were related to documenting code. I don't think that should cause any such errors.

Git diff is here - https://pastebin.com/22tG37SB.

[Evan Patton]

Hi Ankriti,

We use a mix of macOS and Linux for development. The Jenkins server that tests the builds runs on macOS. We don't typically test on Windows, so occasionally these platform-specific bugs get introduced (although we do try to fix them when they are reported)..

Cheers,

Evan

     [java] WARNING: YAIL compiler - ZIPALIGN execution failed.

BUILD FAILED

/home/ankritisachan/app-inventor/appinventor-sources/appinventor/build.xml:21: The following error occurred while executing this line:

/home/ankritisachan/app-inventor/appinventor-sources/appinventor/buildserver/build.xml:180: Java returned: 1

How can I fix this?

This is because the Linux executables are 32 bit, so you need to install  the 32-bit compatability libraries for your system. There are other threads in the forum with example commands (you might want  to put in a PR with updated readme instructions once you're up and running).

Okay, sure. Thanks.

Also, I think that Windows build system failed for me, earlier due some messed up submodules. I don't know how that happened but even on a clean branch, I still get to see some change in commit while doing git diff. Something like -

 git diff

I don't know if this is related to the cause of build failure.

Is there something like submodule versions? Do different branches have different submodule versions? What did I mess up here?

Currently, I got a master branch which was not failing while build, so I rebased my branch(which was earlier on ucr) onto master and it built successfully. Again, I don't know why that happened. Can you figure out what could have happened here? Does doing that made any difference to the build system?

But, now I faced another issue. After running the main server, when I created a new project and tried to open it, I faced an internal server error. 

Description here -

notes = Browser: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/73.0.3683.103 Safari/537.36
foundIn = nls-1318-gbec5507f
faultData = java.lang.UnsupportedOperationException: unknown component: Switch
projectId = -1

What should I do here?

P.S. All the above description is for Windows.

Hi Ankriti,

for your last issue, the one about the Switch component, it might be
happening if the Switch component is not yet in master but it is only
in ucr (which I am not certain it is the case).

If you created a project after working in ucr, and try to load it in a
server compiled off master with no Switch component, that's what you
may get.

You can trash the project and start a new one. Also make sure you are
not being tricked by the browser's cache. In development tools -->
settings --> Network you can set 'Disable cache (while DevTools is
open)', so if you have the dev tools open, the cache will be
invalidated when you reload.

As far as I recall, ucr only gets merged into master when a
'component' release is prepared. So for the most part, ucr may be
ahead of master for component related code, and behind master for
other changes that do not affect components.

cheers,
José

Hi Jose,

Thanks for the information. I disabled cache. Still the same problem. So, I guess error might be because of the difference between master and ucr like you said.

So, now I am stuck with a problem which looks something like -

If my branch is rebased onto master, it will build but old or new projects won't open.

If my branch is rebased onto ucr, it won't even build in the first place.

I will do the needful in Linux, as Evan told, and try running it there.

[Evan Patton]

If you haven't run ant clean then the .class files for switch, etc. will still be bundled in if you had previously compiled on ucr.

Regards,

Evan

Don't do $ ant without first getting the Auth Key in place, atleast once. Just do this:

first cd your way into the appinventor folder, then from there do:

$ ant MakeAuthKey

You should get "BUILD SUCCESSFUL". Sweeeet!!

Afterwards, to compile your stuff, just do:

$ ant

You should get the glorious "BUILD SUCCESSFUL" thing.

Enjoy AppInventor
