flutter - 错误：类路径中的某些运行时 JAR 文件具有不兼容的版本。考虑从类路径中删除它们

Question

运行 flutter build apk 时，我得到以下信息：

\n

w: Runtime JAR files in the classpath should have the same version. These files were found in the classpath:\n    C:/Users/username/.gradle/caches/modules-2/files-2.1/org.jetbrains.kotlin/kotlin-stdlib-jdk7/1.3.50/50ad05ea1c2595fb31b800e76db464d08d599af3/kotlin-stdlib-jdk7-1.3.50.jar (version 1.3)\n    C:/Users/username/.gradle/caches/modules-2/files-2.1/org.jetbrains.kotlin/kotlin-stdlib/1.3.50/b529d1738c7e98bbfa36a4134039528f2ce78ebf/kotlin-stdlib-1.3.50.jar (version 1.3)\n    C:/Users/username/.gradle/caches/modules-2/files-2.1/org.jetbrains.kotlin/kotlin-stdlib-common/1.3.50/3d9cd3e1bc7b92e95f43d45be3bfbcf38e36ab87/kotlin-stdlib-common-1.3.50.jar (version 1.3)\n    C:/Users/username/.gradle/caches/modules-2/files-2.1/org.jetbrains.kotlin/kotlin-stdlib/1.5.10/da6a904b132f0402fa4d79169a3c1770598d4702/kotlin-stdlib-1.5.10.jar (version 1.5)\n    C:/Users/username/.gradle/caches/modules-2/files-2.1/org.jetbrains.kotlin/kotlin-stdlib-jdk7/1.5.10/c49d0703d16c6cb1526cc07b9b46486da1dd8a60/kotlin-stdlib-jdk7-1.5.10.jar (version 1.5)\n    C:/Users/username/.gradle/caches/modules-2/files-2.1/org.jetbrains.kotlin/kotlin-stdlib-common/1.5.10/6b84d926e28493be69daf673e40076f89492ef7/kotlin-stdlib-common-1.5.10.jar (version 1.5)\nw: Some runtime JAR files in the classpath have an incompatible version.

我已经完成了我在网上和这个小组中找到的一些建议，但到目前为止没有任何效果。在 android\\build.gradle 中：

\n

buildscript {\n    ext.kotlin_version = '1.5.10'\n    repositories {\n        google()\n        jcenter()\n    }\n\n    dependencies {\n        classpath 'com.android.tools.build:gradle:4.2.1'\n        classpath 'com.android.tools.build:gradle:4.2.1'\n        classpath "org.jetbrains.kotlin:kotlin-stdlib:1.5.10"\n        classpath "org.jetbrains.kotlin:kotlin-stdlib-common:1.5.10"\n        classpath "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.5.10"\n\n    }\n}\n

\n

在 app\\build.gradle 中：

\n

dependencies {\n    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.5.10"\n    implementation "org.jetbrains.kotlin:kotlin-stdlib:1.5.10"\n    implementation "org.jetbrains.kotlin:kotlin-stdlib-common:1.5.10"\n}\n

\n

我还运行了 flutter pub Upgrade --major-versions

\n

我之前已经能够毫无问题地构建我的 apk，我将 workmanager 添加到我的 pubsec.yaml 中，这个问题开始出现，但是我删除了该包，问题仍然存在。任何帮助都很感激我已经坚持了一段时间了！

flutter doctor -v 的输出

Answer 1

使用

ext.kotlin_version = '1.6.10'

并将 jdk7 更改为 Java jdk8

前

dependencies {
 implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
}

后

dependencies {
 implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk8:$kotlin_version"
}

Answer 2

在遇到同样的问题后回到这里，无法弄清楚我第一次做了什么，但基本上我需要弄清楚如何升级 android/app/build.gradle 中的 gradle 版本：（classpath 'com.android.tools.build:gradle:7.3.1'我在 4.2 上有这个。 2）

然后我必须在 android/gradle/wrapper/gradle-wrapper.properties 中进行相同的更新，如下所示distributionUrl=https\://services.gradle.org/distributions/gradle-7.4-all.zip

然后构建没有错误。
