在Android Studio中，我转到文件->项目结构"，并将JDK的位置从更改为

我也将我的项目上传到了Github，以防有人需要查看.

解决方案
就我而言，这是在Java更新后开始发生的.事实证明，JRE已更新，但JDK没有更新.
尝试:安装新的JDK更新，卸载旧版本，然后重新打开任何shell/ps/cmd会话/窗口.可能有必要杀死现有的Gradle守护程序，但它应该足够聪明以至于不能重用它们.再次尝试构建！
Sidenote - this post is similar (but not identical) to compileReleaseKotlin fails with java.lang.ClassNotFoundException: com.sun.tools.javac.util.Context, but I thought I'd make my own post with more details about my situation in order to get the best feedback possible. Also, I tried all the solutions in that post, and none of them worked.
I am trying to generate an unsigned release APK for my app. To do that, I use the command gradlew assembleRelease.
I get the following error:

Here's some more information about my current situation:
I'm using Windows 10.
This is the result of gradlew assembleRelease --scan. It contains a lot of detailed information that could be useful for debugging.
https://scans.gradle.com/s/sohrhovsc676e/
In Android Studio, I went to "File -> Project Structure" and changed my JDK location from
"C:\Program Files\Android\Android Studio\jre" (embedded JDK)
to
"C:\Program Files\Java\jdk1.8.0_172" (JDK 8), which I got from here.
This failed to solve the problem.
I have also added "C:\Program Files\Java\jdk1.8.0_172\bin" to my System Path variable.
I also uploaded my project to Github, incase anyone needs to see it. https://github.com/vedantroy/recyclerview-test
Also, I previously tried replacing implementation"org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version" with implementation"org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version", but that didn't work either.
Edit 1 -
I tried switching my Build Variant to "release" and then building an APK and that seemed to work. However, I'm not sure if that produces the same result as gradlew assembleRelease
解决方案
In my case, this started happening after a Java update. It turns out the JRE was updated but the JDK was not.
Try: install the new JDK update, uninstall old versions, and reopen any shell/ps/cmd sessions/windows. It may be necessary to kill existing Gradle daemons but it should be smart enough not to reuse them. Try your build again!
这篇关于gradlew assembleRelease因java.lang.ClassNotFoundException而失败:com.sun.tools.javac.util.Context的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
