I tried downloading the google-fhir repo and running generate-proto.sh, which generated a bunch of java files in ~/fhir-master/proto/stu3/target/com/google/fhir/stu3/proto which won't compile. Many objects cannot be resolved: com.google.fhir.stu3.proto.ReferenceOrBuilder getCoverageOrBuilder();, com.google.fhir.stu3.proto.PositiveInt getPriority();, etc.
At some point, I also generated a bunch of classes (not sure how now, but I think it was with hazel. if you know, please tell me) in com/google/fhir/stu3/proto. However when I try to use these classes to extract the schema, none of the symbols can be found: java.lang.NoClassDefFoundError: com/google/fhir/stu3/proto/IdOrBuilder and error: cannot find symbol, etc.
How do I get all the dependencies to work? How could this possible work out of the box?
Your question is kind of confusing based on the code and explanation but I will answer your question. If you are compiling your avro schema to java class you should be able to get the schema like this
Account.$SCHEMA
Now if you are asking how can create and schema from a POJO in java, you can do it like this
Schema schema = ReflectData.get().getSchema(YourClass.class);
About the exception that you are getting, is hard to help you without context or more code to understand what you are trying to do and how.

I know it can be done, but I'm having trouble getting it working. I'm still finding my feet with Haskell.
I tried using postgresql-typed, but it wouldn't compile. They don't enable the QuasiQuotes extension, so I don't understand how their code would ever compile. It also fails with an error on the useTPGDatabase statement. I cloned the library's source code from Github, but their tests failed to compile using stack with exactly the same errors.
I considered using hasql-th, but it's not on stackage.org, which immediately puts it in the "too hard basket.". I considered switching to nix but that seems like even more effort.
Does somebody have a reliable recipe for getting an environment working that type-checks SQL at compile time in Haskell?
I considered using hasql-th, but it's not on stackage.org, which immediately puts it in the "too hard basket."
All you need to do is add the latest version of hasql-th to the extra-deps section of your stack.yaml file and all other deps that Stack will suggest to you when you build.
In the end your stack.yaml file should look something like this:
resolver: lts-17.9
extra-deps:
- hasql-th-0.4.0.8
- headed-megaparsec-0.1.0.4
- postgresql-syntax-0.3.0.3
Anticipating a question in the spirit of "Why is it not listed on Stackage?" It's just that nobody has gotten to list these packages yet.
When serving lit-element components with nollup then I keep getting the following error in the browser console that I am not able to track down:
toast-messages.js:56 Uncaught TypeError: modules[number] is not a function

Can anyone point me in the right direction? (I can share my rollup.config.js if required)
This error means that a module has been requested, but there's no module with the specified id (number) included in the bundle. This can happen for a variety of reasons:
There's a call using require passing an invalid id.
Passing a string or something other than a number into require.
Using a library that was compiled to CommonJS but was not transformed to ESM.
It's likely that you're missing the CommonJS plugin, or if you are, then the CommonJS isn't able to catch the require call and convert it. The latter can happen because of obfuscation in the library code. CommonJS plugins work by using static analysis. It would be very difficult for the plugin to transform the following:
var r = require;
r('my-library-code');
Without executing the code, it would be difficult for static analysis to track this. A best effort attempt can be made, but there will be always a situation where it could fail.
So here's the following steps you should take:
* Confirm that the CommonJS plugin is being used.
* If it is, check the file in node_modules for unusual patterns.
* If there is, file an issue with the CommonJS plugin maintainer and see if it's possible to solve, and if not, you might need to contact the maintainer for the toast-message library.
I do realise I'm posting this very late, but better to answer later than never! To avoid this vague error in the future, in 0.10.2 of Nollup I've added a user friendly error that list some things to check for.
Hope this helps!
I just finished skating around that infamous "cannot load main class start" thing, and I got blindsided with a sea of errors:
A friend suggests it might have something to do with com.google, but ultimately can't help me.
I haven't made a single alteration to any of the code so far. Eclipse just started up not being able to run and stayed that way. I think there's a way to fix it but it would require making acute changes at the sight of every single error; work that could be wiped by a cleanup if I'm proved wrong.
Anyone have a clue what the issue is? Thank you for the trouble.
UPDATE: Adding guava as a library relieved the error involving com.google, but threw in a handful of others. This one class file contains 3 of the most common unresolved types I've seen scattered throughout: Logger/LogManagaer, PropertyMap, and CrashReport
Your general problems revolve around not having dependencies in the build path. Eclipse's error messages are pretty clear about this; e.g. if a package name is underlined in red and can't be found, then that means it can't be found, and the obvious solution is to add the library that provides it, so that it can be found.
In virtually all cases here, a Google search for the missing packages and classes will lead you to the packages that contain it.
For each unresolved dependency, find the library, add it to the build path, then move on.
I also suggest consulting the documentation that comes with the source code you are attempting to compile, which often simply lists the dependencies, thus saving you the trouble of hunting them down as you go.
While we could do the internet searches for you and hash this out one step at a time, it's both better and faster for you to do it yourself. Better because if you're messing around with Minecraft source, having at least a basic knowledge of how your tools work is going to help you (I also suggest some of the material at http://docs.oracle.com/javase/tutorial/). Faster because the turnaround time of typing package names into the Google search box is a heck of a lot faster than constantly updating your question here and waiting for replies.
It looks like you are missing the Google Collections package, which now is called Guava.
Download the jar file, and add it as a library.
I am porting an old Java code base to OSGI. In the old code base there is dynamic code generation used. Example a string is compiled to generate Java classes using
com.sun.tools.javac.Main.compile.
I was reusing the same code and added com.sun.tools.javac in etc/custom.properties -> org.osgi.framework.system.packages.extra:= com.sun.tools.javac.Main of Karaf.
During runtime I get the exception java.lang.NoClassDefFoundError: com/sun/tools/javac/Main
Could anyone please help me out with some suggestions to overcome the problem.
I don't know Karaf but why do you use := instead of just = in the property setting? Also, the property value is a list of package names, not type names. So the interesting package is "com.sun.tools.javac".
I've got a really strange error and any light that anyone can shed on this would be greatly appreciated.
I made some changes to some VB6 source which builds a COM object. The automated build which builds our app returned an error. No problem I thought--I'll just back out my changes. Well backing out my changes isn't making the problem go away.
Specifically when I attempt to build the app via a .vbg file, with a command line like path\to\vb6\vb6 ProjectFile.vbg /make
I get a message
"Compile Error in File '', Line : Object library
invalid or contains references to object definitions that could not be
found."
As I said, I reverted the source code so I'm really stumped as to why this error is still occurring. Any VB6 gurus around who might be able to point me at an answer?
I can post the exact code in question but the fact that it was building correctly, stopped building correctly and now refuses to build correctly makes me think this is not a problem with my code but rather some problem in the environment. Like something got put in the registry as a result of the previous build error.
Any tips, hints, or suggestions greatly welcome. I realize my question is a bit sketchy but I'm not even sure what's important to include and what isn't.
EDIT 1:
Thanks for the excellent suggestions guys. I think it is something to do with VB6 doing some sort of auto-registration.
Just to add a bit more detail: this problem does not occur when I build the referenced vbp file from the IDE. It only happens on the make on the .vbg which contains the vbp. Also the build tool in question automatically pulls latest source and the error happens on both my local box and the dedicated build box.
EDIT 2:
Hi again all,
The release engineering fellow figured out how to get this to build in his build environment so it's currently ok. Once we're past this crunch, I'll try to interrogate him about what he did and share the details with everyone.
Thanks again for all the great suggestions. This is what's so great about SO; that is, I asked about a 10-year-old technology and I got several great and on-point ideas.
Make sure that the VBG and all the VBP's got rolled back as well. That error is consistent with a project trying to reference a CLSID that is no longer valid for the dependency. Have you tried loading up the project group and building from the IDE, if that works and you save and check in all the changes to the group and project files, you might be fixed up.
I'm guessing the fact that you mention that it was a COM component might be the source of the problem. If any of the public method's or properties have changed then I seem to remember that VB6 will change the interface GUIDs and auto register the new ones.
My suggestion would be to check the registry to look for any mention of the component name, make a note of any associated CLSIDs, back up the registry, and then delete the references.
As cmsjr mentions it could also be a bad CLSID reference in your .vbp files.
The other option is that the failure has caused a problem with some .tlb (type library) or olb (object library) files.
The best thing to do is move all your compatibility DLL to a separate and combined directory. The reason for this is control over what VB6 is using to check for binary compatibility. In addition the Typelibs that are generated IMPORT the references. So if you using Binary DLL Ver 10 for compatibility however the import is pulling in Binary DLL Ver 9 you will have issues. By keeping all the libraries in a single folder and pointing your projects to the DLLs in that folder you ensure that the respective TypeLib Import the correct version.
Finally if you have multiple levels of DLL reference each other. You may run into mysterious error where the VB6 is unable to compile using binary compatibility. In such cases you need to compile the lowest DLL in the hierarchy (Utility DLL perhaps) copy it over into the compatibility folders. Work your way up the chain until everything compiles in one shot again.
This is because if have DLL A reference DLL B which Reference DLL C. VB6 will get sometimes get confused if you make a change to A and C. will compile fine but A will not until the compatibility libraries are updated.
Hunt down and delete any .obj and .exp files that may be lying around from the previous failed build.
You will have to open the project & re-type in the lines that you changed.
Save the project alongwith VBG and re-compile after that.
I think that will fix it.
EDIT: The idea is that the cls/bas file remember the class (CLSID) that you used. So, if you change the references but don't change the lines in the cls/bas - it is a mismatch of type (what was referenced vs what is typed in cls/bas file).
