错误: 在 Ionic 3中找不到 org.jetbrains.kotlin: kotlin-stdlib-jdk8:1.3.60-eap-25

在为 Android 开发 Ionic 3应用程序时，我突然出现了以下错误。

Could not find org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.3.60-eap-25

我们有一个来自 Android Studio 给你的解决方案，但是在我用下面的代码修改 build.gradle 之后，我仍然得到了这个错误。

buildscript {
repositories {
...
maven { url 'https://dl.bintray.com/kotlin/kotlin-eap' }
}
}


allprojects {
repositories {
...
maven { url 'https://dl.bintray.com/kotlin/kotlin-eap' }
}
}

在我更新了 Cordova 并添加了上述解决方案之后，build.gradle 文件看起来如下所示。

buildscript {
repositories {
google()
jcenter()
maven { url 'https://dl.bintray.com/kotlin/kotlin-eap' }
}


dependencies {
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files


classpath 'com.android.tools.build:gradle:3.3.0'
}
}


allprojects {
repositories {
google()
jcenter()
maven { url 'https://dl.bintray.com/kotlin/kotlin-eap' }
}


//This replaces project.properties w.r.t. build settings
project.ext {
defaultBuildToolsVersion="28.0.3" //String
defaultMinSdkVersion=19 //Integer - Minimum requirement is Android 4.4
defaultTargetSdkVersion=28 //Integer - We ALWAYS target the latest by default
defaultCompileSdkVersion=28 //Integer - We ALWAYS compile with the latest by default
}
}


task clean(type: Delete) {
delete rootProject.buildDir
}

还是同样的错误。

Here is the solution.

The problem was exactly the maven repository (here), but the issue was with the build.gradle from the cordova-support-google-services plugin, so I added the required line and everything is ok now, I've already created a pull request to the original repo (here). But in the meantime you can do what I did, just replace in the package.json the current versión with my repo:

Before:

...
"cordova-support-google-services": "^1.3.1",
...

After:

...
"cordova-support-google-services": "https://github.com/LuisEGR/cordova-support-google-services.git",
...

after that you will have to:

  • Remove folders platforms and plugins
  • run npm install

This is a temporal solution while the pull request to the main repo gets accepted and the npm package updated

and that's it, now you can build your project again.

I'm using Ionic 4, and some plugins require cordova-support-google-services, in case you don't have it in your package.json the error could be with another plugin, if so please add the package.json so we can find out which one is the problem.

UPDATE 24/OCT:

I've changed the solution in my repo as many of you suggested, now the solution consinst just in fixing the dependency: from: com.android.tools.build:gradle:+ to classpath com.android.tools.build:gradle:3.+, this is already in my repo if you want to see what's changed

EDIT 10/28/19:

cordova-support-google-services was updated today to version 1.3.2 which changes the classpath from classpath 'com.android.tools.build:gradle:+'

to

classpath 'com.android.tools.build:gradle:3.+'

which seems to fix the kotlin error

Original Answer

I got mine to build successfully by doing the following:

I edited platforms->android->cordova-support-google-services->myAppName-build.gradle

and changed

maventCentral()

to

    maven { url "https://maven.google.com" }
maven { url 'https://dl.bintray.com/kotlin/kotlin-eap' }

That solved the kotlin error then I was getting a different error that I resolved by changing 

classpath 'com.google.gms:google-services:4.2.0'

to

classpath 'com.google.gms:google-services:4.1.0'

It then built successfully.

......
maven { url 'https://dl.bintray.com/kotlin/kotlin-eap' }
}

最佳答案

The problem lies in the cordova-support-google-services plugin for Cordova.

This plugin's build.gradle looks like this as of today (October 24th, 2019): 

dependencies {
classpath 'com.android.tools.build:gradle:+'
classpath 'com.google.gms:google-services:4.2.0'
}

More exactly the problem lies in this dependency:

classpath 'com.android.tools.build:gradle:+'

That is an extremely brittle way of specifying dependencies. The '+' sign here means "fetch the most recent version available in the repo". If a newer version is published in the repo, and it breaks the build, then everyone with this plugin has their projects broken. This happened today. The broken version that is being fetched is com.android.tools.build:gradle:4.0.0. It requires some Kotlin stuff.

That is why you need to ALWAYS freeze dependencies to reliably build your project. Never trust the newer stuff. This dependency compiles fine just as it did yesterday:

classpath 'com.android.tools.build:gradle:3.5.1'

For those using Cordova or Ionic, you can make a quick fix to be able to build the project by freezing the dependency in the file:

<projectroot>/platforms/android/cordova-support-google-services/<project>-build.gradle

This is not a definitive solution though. If you reinstall the android platform via Cordova the error will show up again. The project maintainer should either freeze the dependency or fix it to support gradle 4.0.0. In the meantime just use a fixed fork of this plugin.

As a further temporary fix to follow-up on the suggestion from @MisterSmith, use a hook to re-apply the lock:

<hook src="scripts/fix_android_dep.sh" type="after_platform_add"/>

with this overly wordy bash code:

#!/usr/bin/env bash

Solution for ionic v3 and cordova

@Mister Smith solution solved my problem

you have to go to the file 

platforms/android/cordova-support-google-services

then

Replace

classpath 'com.android.tools.build:gradle:+'

by 

classpath 'com.android.tools.build:gradle:3.5.1'

@Alternative solution I have found is to

setup kotlin in your system :)

None of the above worked for me. I ended up removing the google-services plugin and add it.

cordova plugin rm cordova-support-google-services cordova plugin add cordova-support-google-services

I had to add maven { url 'https://dl.bintray.com/kotlin/kotlin-eap' } both into the top-level build.gradle and into the app module build.gradle. In both cases both into the buildscripts.repositories and in allprojects.repositories

In my case I had the same error first, then a whole bunch of other packages (org.ow2.asm:asm-analysis:4.0@jar, etc...) that could also not be resolved.

The problem was that I upgraded Gradle to v5 (to be able to support the new version of Crashlytic). Doing so, I upgraded the repository to Google(), and deleted the old maven { url ... } entries.

But I also deleted jcenter(), which was still required for a lot of nodes.

Now my repository section looks like this:

buildscript {
repositories {
maven { url "$rootDir/../node_modules/react-native/android" }
google() // Google Maven repository
jcenter()
}
//...

So if someone else is reading this but was not happy with the current accepted solution of downgrading Gradle, check if you have jcenter().

Ps.: I realize this is an old issue but I recently found it while searching on google.
