【问题描述】：

我正在为我的（第一个）Spring Boot 应用程序设置工作流。当它运行时，它会在 run 命令处给出错误。我不太确定要更改什么，因为我对 SpringBoot 或 Java 不太熟悉。

错误：

Error:  Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.10.1:compile (default-compile) on project Workethic: Fatal error compiling: error: invalid target release: 18 -> [Help 1]

我在 IntelliJ 中查看并看到了这个，这与此有什么关系吗？如果是，为什么它对 Github 工作流程很重要？ https://gyazo.com/1ab85231aa6743bc0ef8de28756f40fc

pom.xml:

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>${project.parent.version}</version>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>${maven-compiler-plugin.version}</version>
                <configuration>

                </configuration>
            </plugin>
        </plugins>
    </build>

工作流程：

jobs:
  build:

    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v3
    - name: Set up JDK 11
      uses: actions/setup-java@v3
      with:
        java-version: '11'
        distribution: 'temurin'
        cache: maven
    - name: Build with Maven
      run: mvn clean install

    # Optional: Uploads the full dependency graph to GitHub to improve the quality of Dependabot alerts this repository can receive
    - name: Update dependency graph
      uses: advanced-security/maven-dependency-submission-action@571e99aab1055c2e71a1e2309b9691de18d6b7d6

【解决方案1】：

如果您查看此页面： https://github.com/actions/setup-java#supported-version-syntax 您可以看到 jdk 18 不是 github 工作流程支持的版本，请尝试将其设置为 17。
