在运行脚本时,我在Eclipse控制台中得到以下错误消息:

类已经由最新版本的Java环境(类文件版本53.0)编译,该版本的Java运行时只识别52.0以下的类文件版本。


Java版本:8 IDE: Eclipse Oxygen Firefox版本:46

对于PhpStorm 2022.3尝试:

sudo apt-get purge openjdk-\*
sudo apt install openjdk-19-jdk
export JAVA_HOME=/usr/lib/jvm/java-19-openjdk-amd64
export PATH=$PATH:$JAVA_HOME/bin
/opt/PhpStorm-223.7571.212/bin/phpstorm.sh

53代表java-9,所以这意味着你拥有的任何类都是用javac-9编译的,你可以尝试用jre-8运行它。要么使用javac-8重新编译该类,要么使用jre-9

你可以试试这种方法

javac --release 8 yourClass.java

从spring initizer初始化我的项目时遇到了同样的问题 我们需要匹配java的版本。“build.gradle”中用于运行和编译的sourceCompatibility和jvmTarget。kt”文件。

Sonarqube也有同样的问题

已经由最新版本的Java运行时(类文件版本55.0)编译,这个版本的Java运行时只识别类文件版本52.0

Sonarqube与AzureDevOps错误输出:

我在Sonarcube服务器上安装了Java v11,但错误提示它的构建代理没有Java v11。

我决定将Java v12 bin路径添加到环境变量路径中,以便检测它。重要的是,这需要在构建代理上完成:

对于托管生成代理,您可以安装JDK v11或使用以下PowerShell脚本步骤:

- task: PowerShell@2
  displayName: 'Download and Install Java v11'
  inputs:
    targetType: 'inline'
    script: |
      [Net.ServicePointManager]::SecurityProtocol = [Net.SecurityProtocolType]::Tls12
      $Command = "c:\jdk-11.0.15_windows-x64_bin.exe"
      $Parms = "/s"
      Write-Host [System.IO.File]::Exists($Command)
      if ([System.IO.File]::Exists($Command)) {
        Write-Host 'Downloading Java11.exe'      
        Invoke-WebRequest https://yourOwnUrl.com/jdk-11.0.15_windows-x64_bin.exe -OutFile $Command
      }
      Write-Host [System.IO.File]::Exists($Command)
      & "$Command" $Prms
      [System.Environment]::SetEnvironmentVariable("JAVA_HOME", "C:\Program Files\Java\jdk-11.0.15")
      [System.Environment]::SetEnvironmentVariable("Path", [System.Environment]::GetEnvironmentVariable('Path', [System.EnvironmentVariableTarget]::Machine) + ";$($env:JAVA_HOME)\bin")

对我来说,解决方案是按照安德烈·库兹涅佐夫在https://youtrack.jetbrains.com/issue/IDEA-251407/Failed-to-run-Android-project-in-the-Idea-20203-EAP-OutputBuildAction-has-been-compiled-by-a-more-recent-version-of-the-Java上所说的去做,总结如下:

根本原因:IDEA源码现在是基于Java 11编译的。已知的解决方法是将Java 11配置为Gradle JVM。”(Andrei“库兹涅佐夫”)
