我有一个scala代码，它成功地在jdk13.0.1上本地构建。

s.getValue().stripTrailing()  // s.getValue() returns String

当此代码由github操作生成时，我得到以下错误：

Error:  -- [E008] Not Found Error: /github/workspace/core/src/main/scala/co.blocke.scalajack/yaml/YamlParser.scala:45:96 
Error:  45 |          case "|" | ">"                           => s.getValue().stripTrailing()
Error:     |                                                      ^^^^^^^^^^^^^^^^^^^^^^^^^^
Error:     |                           value stripTrailing is not a member of String

我的操作文件是：

name: Package Build

# This workflow is triggered on pushes to the repository.

on: 
  push:
    branches-ignore:
      - "feature/*"  # don't run build/test against a feature branch -- no SLA there
      - "master"

jobs:
  build:
    name: Build
    runs-on: ubuntu-latest

    steps:
      - name: Checkout repo
        uses: actions/checkout@v2
      - name: Set up JDK 13
        uses: actions/setup-java@v1
        with:
          java-version: '13.0.1'
      - name: Test
        id: sbt
        uses: lokkju/github-action-sbt@master
        with:
          commands: test

striptrailing（）是oracle和OpenJDK13.x库中的字符串方法。
