Description

I faced an build issue when I build the serverless application on my local machine. The pom error show

[ERROR] Non-resolvable parent POM for tally.expense:aws-lambda-get-expenses:49-SNAPSHOT: Could not find artifact tally.

However, this is not a maven issue, because I am able to build my project successfully manually with the maven command.

Steps to reproduce

Clone repository: git@github.com:francis-pang/expense-tally.git
Check out branch feature/aws-sam
Navigate to ./aws-lambda/get-expenses
Build application via command sam build --use-container --template-file template.yaml

Observed result

Hi @francis-pang ,

I tried to re-produce the issue you mentioned, but I ended up having other problems related to maven compiler plugin. After fixing those, the build process for maven completed successfully, but SAM build fails because there were no target/classes directory in the end.

And looking at the template file, CodeUri is pointing to 2 folders up (../../) for the code base of the lambda function. If you have shared dependency I would suggest to publish those packages as another dependency for your lambda function, or use layers.

Please let us know if you have further issues.

francis-pang commented 3 years ago

@mndeveci , I tried to build based on the root folder, in which the template looks as below (partially):

Resources:
  GetDiscrepantExpensesFunction:
    Type: AWS::Serverless::Function # More info about Function Resource: https://github.com/awslabs/serverless-application-model/blob/master/versions/2016-10-31.md#awsserverlessfunction
    Properties:
      Description: 'Retrieve all the mismatching transactions'
      CodeUri: .

However it fails:

[ERROR] [ERROR] Some problems were encountered while processing the POMs: [FATAL] Non-resolvable parent POM for tally.expense:aws-lambda-get-expenses:49-SNAPSHOT: Could not find artifact tally.expense:aws-lambda:pom:49-SNAPSHOT and 'parent.relativePath' points at wrong local POM @ line 5, column 13 @ [ERROR] The build could not read 1 project -> [Help 1] [ERROR] [ERROR] The project tally.expense:aws-lambda-get-expenses:49-SNAPSHOT (/tmp/tmpgjbfjznj/pom.xml) has 1 error [ERROR] Non-resolvable parent POM for tally.expense:aws-lambda-get-expenses:49-SNAPSHOT: Could not find artifact tally.expense:aws-lambda:pom:49-SNAPSHOT and 'parent.relativePath' points at wrong local POM @ line 5, column 13 -> [Help 2]

I found out that the SAM build command copy all the content which the template.yaml is located into a directory inside /tmp/. However it does not copy the root directory, where the parent pom resides. Due to this lack of dependency, the build fails.

Is it a technical restriction that there cannot be parent pom dependency in SAM application pom file?

mndeveci commented 3 years ago

@francis-pang ,

I would suggest to move all source files of your lambda function under another folder. So your root folder will look like this;

.
├── YourFunctionCode
│   ├── pom.xml
│   └── src
│       ├── main
│       │   └── java
│       │       └── ...
│       └── test
│           └── java
│               └── ...
└── template.yaml

And if you have dependencies of other projects, I would rather put them into a repository so that build can pull them, or create Lambda Layer(s) to share common code between different functions.

CoshUS commented 3 years ago

Closing. Feel free to reopen if there is further issue.

emaayan commented 3 years ago

from my POV this poses a major restriction on developing SAM with java, we cannot use a parent pom which holds common definitions for plugins and build life cycle not to mention be able to have shared dependencies (because after all they would have to be in a sibling folder, and we can't use layers because sam doesn't build those autoamtically (it would if we could have used reactor builds, that would build that dependency first

lestephane commented 3 years ago

SAM CLI is synonym with head banging on maven multi-modules project...

...which are the bread and butter of developers who cleanly architect their code into multiple modules, and don't want to waste time mvn installing or (worse) releasing artifacts just to be able to deploy a serverless function during local development.

the sam build command mvn installs all modules to my local .m2 repostory which I go to great pains to kee free of manually mvn installed dependencies.
the --debug flag does not output what is actually going on
- copying an entire tree to/tmp, wait, what? debug output should include copying /blah/** to /tmp/blah... so I can troubleshoot more easily what's going on, and then bug you about the next invalid assumption in your maven support.
- to make matters worse, the /tmp directory where you copy things is deleted before I ever get the chance to look into it to figure out what is going on.
- the JavaMavenWorkflow steps do not actually show what exact maven command was run, everything is a black box. 2021-02-11 14:54:16,250 | Running workflow 'JavaMavenWorkflow' 2021-02-11 14:54:16,251 | Running JavaMavenWorkflow:CopySource <<<<< What command? 2021-02-11 14:54:16,313 | JavaMavenWorkflow:CopySource succeeded 2021-02-11 14:54:16,313 | Running JavaMavenWorkflow:MavenBuild <<<<< What command? 2021-02-11 14:54:38,600 | JavaMavenWorkflow:MavenBuild succeeded 2021-02-11 14:54:38,600 | Running JavaMavenWorkflow:MavenCopyDependency <<<<< What command? 2021-02-11 14:54:40,834 | JavaMavenWorkflow:MavenCopyDependency succeeded 2021-02-11 14:54:40,834 | Running JavaMavenWorkflow:MavenCopyArtifacts <<<<< What command? 2021-02-11 14:54:40,834 | JavaMavenWorkflow:MavenCopyArtifacts failed
the poster is advised to change his project structure from a perfectly valid maven project structure, and then the issue is closed. How does that fix the problem? In order to show how the structure you impose on project structure is totally arbitrary, I expanded the generated java11 maven hello-world from sam cli with a second identical helloworld function, and added a 3rd top-level shared code module.

@mndeveci could you please help with this? Multi-module maven support is poor.

@pengfeiwang-cn can you give an example template that we can use to re-produce the issue that you are facing?

First message in this thread has this example (git@github.com:francis-pang/expense-tally.git), is yours same as that one?

Found a workaround but this is still painfull... 👍 for this feature to be implemented.

the workaround:

from-parent-pom$ mvn install

it will copy the parent-pom in ~/.m2/... then sam build will work

aws / aws-sam-cli

Unable to build due to parent relative path #2289
