Gradle Ktlint 插件在 Java 16 上失败

Question

升级到 Java 16 后，我无法使 ktlint gradle 插件工作。它在扔

Execution failed for task ':runKtlintCheckOverMainSourceSet'.
A failure occurred while executing org.jlleitschuh.gradle.ktlint.worker.KtLintWorkAction
   java.lang.ExceptionInInitializerError (no error message)

Exception is:

我知道这是由更严格的模块检查 (JEP 396) 引起的，但我无法为插件设置 JVM 参数。我试过了：

• 设置环境变量JAVA_OPTS=--illegal-access=warn
• 在gradle.properties 中设置org.gradle.jvmargs=--illegal-access=warn -Dkotlin.daemon.jvm.options=--illegal-access=warn

但是这两种尝试都没有帮助，我没有想法。

Answer 1

Gradle 6.x 似乎不支持 Java 16，Gradle 7 将支持。

Answer 2

您可以根据migration guide更新Gradle插件以获取最新版本：

gradle wrapper --gradle-version 7.0

这应该可以解决此错误消息。否则，您也可以更改文件gradle/wrapper/gradle-wrapper.properties中的版本。

distributionUrl=https\://services.gradle.org/distributions/gradle-7.0-bin.zip

我还将kotlin("jvm") 等kotlin 插件更新为最新版本1.4.32。
