How fix a duplicate src folder when build a java project in aws codebuild?

SOLVED

Hello,

I am implementing a lambda function with the tool of continuous integrations of aws . CodeSource , CodeBuild CodePipeLine.

After set up all, when i test the lambda the result is

{
  "errorMessage": "Class not found: com.ad.client.App",
  "errorType": "java.lang.ClassNotFoundException"
}
START RequestId: e8e8db05-5631-4c98-bb7e-6b388ff61af5 Version: $LATEST
Class not found: com.ad.client.App: java.lang.ClassNotFoundException
java.lang.ClassNotFoundException: com.ad.client.App
	at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
	at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
	at java.lang.Class.forName0(Native Method)
	at java.lang.Class.forName(Class.java:348)

END RequestId: e8e8db05-5631-4c98-bb7e-6b388ff61af5
REPORT RequestId: e8e8db05-5631-4c98-bb7e-6b388ff61af5	Duration: 110.17 ms	Billed Duration: 200 ms 	Memory Size: 128 MB	Max Memory Used: 68 MB	

All stage of Pipeline are succeeded(Source , Build , Deploy)

If a load the jar directly in the lambda console the result is the correct
I review the log of the build and found this:

/codebuild/output/src748698927/src 

INFO] skip non existing resourceDirectory /codebuild/output/src748698927/src/src/main/resources 

In some portion of code show me that the path src is duplicated, i don't know if it has something to related with the problem

My config files are:

template.yaml

AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31

Resources:
  FtcClientFunction:

    Properties:

      CodeUri: ./

buildspec.yml

phases:
  install:
    runtime-versions:
      java: openjdk8
  build:
    commands:
      - echo Build started on `date`
      - mvn test
      - export BUCKET=my-bucket-for-test
      - aws cloudformation package --template-file template.yaml --s3-bucket $BUCKET --output-template-file outputtemplate.yaml
    finally:
      - echo THE PATH WORK IS !!!
      - pwd
      - echo The list of file is !!
      - ls
      - echo CODE BUILD SRC DIRECTORY
      - echo $CODEBUILD_SRC_DIR
  post_build:
    commands:
      - echo Build completed on `date`
      - mvn package
artifacts:
  files:
    - target/ftc-client-1.0-SNAPSHOT.jar
    - template.yaml
    - outputtemplate.yaml
  discard-paths: yes

appspec.yml

version: 0.0
os: linux
files:
  - source: target/ftc-client-1.0-SNAPSHOT.jar
    destination: /tmp

The source code structure is :
/fclient/src/main/java/com/ad/App.java
/tclient/buildspec.yml
/fclient/pom.xml
/fclient/template.yaml

thank for everyone whom can give me a cue

Answer:
The problem wasn't the duplicate folder,
This is the solution , It is necessary to unzip the jar in the root of my source .

version: 0.2
phases:
  install:
    runtime-versions:
      java: openjdk8
  pre_build:
    commands:
      - echo Test started on `date`
      - mvn clean compile test
  build:
    commands:
      - echo Build started on `date`
      - export BUCKET=my-bucket-for-test
      - mvn package shade:shade
      - mv target/ftc-client-1.0-SNAPSHOT.jar
      - unzip ftc-client-1.0-SNAPSHOT.jar
      - rm -rf target tst src buildspec.yml pom.xml ftc-client-1.0-SNAPSHOT.jar
      - aws cloudformation package --template-file template.yaml --s3-bucket $BUCKET --output-template-file outputtemplate.yaml
  post_build:
    commands:
      - echo Build completed on `date` !!!
artifacts:
  files:
    - tarjet/ftc-client-1.0-SNAPSHOT.jar
    - template.yaml
    - outputtemplate.yaml
