Trying to fix the problems for Tekton Script

Here are three scripts for Tekton. It did not find git directory and compile with mvn due to the missing pom.xml. I tried to fix the problems by revising task, pipeline and pipelinerun but it is not fixed. Where am I supposed to revise the script to fix the issue?

I tried to fix the workspace path and used static path to resolve the issue; however, it did not work.

Task:

apiVersion: tekton.dev/v1beta1kind: Taskmetadata:  name: maven-buildspec:  workspaces:    - name: source  params:    - name: package      type: string  steps:    - name: build      image: maven:3.8.6-openjdk-11      script: |        #!/bin/sh        echo "=== Checking workspace contents ==="        ls -lah $(workspaces.source.path)        # 저장소폴더로이동        cd $(workspaces.source.path)/tekton-tutorial-greeter        # 프로젝트가있는지확인        if [ ! -f "pom.xml" ]; then          echo "ERROR: pom.xml not found! Exiting..."          exit 1        fi        mvn clean package        cp target/*.jar $(workspaces.source.path)/$(params.package).jar

Pipeline:

apiVersion: tekton.dev/v1beta1kind: Pipelinemetadata:  name: greeter-maven-build-pipelinespec:  params:    - name: repo-url      type: string      default: "https://github.com/gitops-cookbook/tekton-tutorial-greeter.git"    - name: revision      type: string      default: "main"    - name: image-name      type: string      default: "greeter-app"  workspaces:    - name: shared-workspace  tasks:    - name: fetch-source      taskRef:        name: git-clone      params:        - name: url          value: "$(params.repo-url)"        - name: revision          value: "$(params.revision)"      workspaces:        - name: output          workspace: shared-workspace    - name: build-and-package      taskRef:        name: maven-build      runAfter:        - fetch-source      params:        - name: package          value: "$(params.image-name)"      workspaces:        - name: source          workspace: shared-workspace

pipelinerun:

apiVersion: tekton.dev/v1beta1kind: PipelineRunmetadata:  name: greeter-maven-build-runspec:  pipelineRef:    name: greeter-maven-build-pipeline  workspaces:    - name: shared-workspace      emptyDir: {}  params:    - name: repo-url      value: "https://github.com/gitops-cookbook/tekton-tutorial-greeter.git"    - name: revision      value: "master"    - name: image-name      value: "greeter-app"
