android - e : [kapt] 'com.sun.tools.javac.util.Context' class can't be found ('tools.jar' is absent in the plugin classpath). Kapt 不起作用

Question

我的项目之前一直运行良好，直到我升级到 API 28并重构为 Androidx .首先我认为我必须解决问题代码，因为重构后 Unresolved reference 代码太多。在我解决了很多问题后，我仍然收到错误

org.gradle.initialization.ReportedException: org.gradle.internal.exceptions.LocationAwareException: Execution failed for task ':app:kaptGenerateStubsDevKotlin'.
    at org.gradle.initialization.DefaultGradleLauncher.doBuildStages(DefaultGradleLauncher.java:145)

    at org.gradle.internal.invocation.GradleBuildController$1.call(GradleBuildController.java:75)
    ... 30 more

所以从gradle控制台我得到这样的错误

从那个错误中，我得到这样的错误

e: [kapt] 'com.sun.tools.javac.util.Context' class can't be found ('tools.jar' is absent in the plugin classpath). Kapt won't work.
:app:kaptGenerateStubsDevKotlin FAILED

所以，我认为这是我的代码无法编译成功的问题

这是我的 build.gradle

Answer 1

您是否检查了您的 jdk 路径，其中文件夹名称包含特殊符号，例如“+”，我更改为“_”。错误得到修复。
示例:文件夹名称为 1.8.0+282 -> 1.8.0_282。
PS:
如果您使用以下软链接(soft link):/Library/Java/JavaVirtualMachines/openjdk-8.jdk ，您应该更新链接:

cd /Library/Java/JavaVirtualMachines/
sudo rm openjdk-8.jdk
sudo ln -s /usr/local/Cellar/openjdk@8/1.8.0_282/libexec/openjdk.jdk openjdk-8.jdk
