在build.gradle(app)中更新如下:(为我工作)

 kotlinOptions {
        jvmTarget = '1.8'
    }

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")

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。

刷新gradle依赖为我工作:右键单击项目-> gradle ->刷新gradle项目。

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

在Intellij中构建Jar后，我在控制台遇到了类似的问题。使用Java配置更新到新版本(Windows -> Configure Java -> update -> update Now)不起作用，并且停留在1.8版本(Java 8)。

为了在本地切换到最新版本，我必须从https://www.oracle.com/uk/java/technologies/javase-jdk15-downloads.html安装Java 15 JDK，并将其添加到我的Java运行时环境设置中。
