[英]How to run the Gradle kotlin-dsl plugin in an offline environment?
Because of reasons, the machine I'm developing on, is not connected to the internet.由于某些原因,我正在开发的机器没有连接到互联网。
I have a local copy of all dependencies for the app and the build script.我有应用程序和构建脚本的所有依赖项的本地副本。 I want to run Gradle with Kotlin scripts, and specifically, the
kotlin-dsl
gradle plugin.我想用 Kotlin 脚本运行 Gradle,特别是
kotlin-dsl
gradle 插件。 For some reason, just downloading the dependencies, is not enough.出于某种原因,仅下载依赖项是不够的。
I currently have:我目前有:
<dependency>
<groupId>org.gradle.kotlin.kotlin-dsl</groupId>
<artifactId>org.gradle.kotlin.kotlin-dsl.gradle.plugin</artifactId>
<version>1.4.9</version>
<type>pom</type>
</dependency>
<dependency>
<groupId>org.gradle.kotlin</groupId>
<artifactId>gradle-kotlin-dsl-plugins</artifactId>
<version>1.4.9</version>
</dependency>
<dependency>
<groupId>org.jetbrains.kotlin</groupId>
<artifactId>kotlin-compiler-embeddable</artifactId>
<version>1.4.20</version>
</dependency>
<dependency>
<groupId>org.jetbrains.kotlin</groupId>
<artifactId>kotlin-stdlib-jdk8</artifactId>
<version>1.4.20</version>
</dependency>
<dependency>
<groupId>org.jetbrains.kotlin</groupId>
<artifactId>kotlin-sam-with-receiver</artifactId>
<version>1.4.20</version>
</dependency>
<dependency>
<groupId>org.jetbrains.kotlin</groupId>
<artifactId>kotlin-gradle-plugin</artifactId>
<version>1.4.20</version>
</dependency>
<dependency>
<groupId>org.jetbrains.kotlin</groupId>
<artifactId>kotlin-scripting-compiler-embeddable</artifactId>
<version>1.4.20</version>
</dependency>
(don't ask why that's in Maven format, but it should get the message across) (不要问为什么这是 Maven 格式,但它应该传达信息)
But in offline runtime, running any Gradle task fails with但是在离线运行时,运行任何 Gradle 任务都会失败
FAILURE: Build failed with an exception.
* Where:
Build file '<path>/build.gradle.kts' line: 1
* What went wrong:
Plugin [id: 'org.gradle.kotlin.kotlin-dsl', version: '1.4.9'] was not found in any of the following sources:
- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Plugin Repositories (could not resolve plugin artifact 'org.gradle.kotlin.kotlin-dsl:org.gradle.kotlin.kotlin-dsl.gradle.plugin:1.4.9')
Searched in the following repositories:
Gradle Central Plugin Repository
So, if anyone knows which other dependencies I need, or where to look to find out, that would be greatly appreciated.因此,如果有人知道我需要哪些其他依赖项,或者在哪里可以找到,那将不胜感激。
I have tried to reproduce your setup.我试图重现您的设置。 I generated a new Gradle project with
gradle init
, selecting a simple library written in Kotlin using the Gradle Kotlin DSL.我使用
gradle init
生成了一个新的 Gradle 项目,选择了一个使用 Gradle Kotlin DSL 用 Kotlin 编写的简单库。
I am in an environment (a docker container) without any internet connection (container is started with --network none
).我在一个没有任何互联网连接的环境(一个 docker 容器)中(容器以
--network none
启动)。
I am using a recent version of Gradle ( 7.3.1
) and I can not reproduce your exact issue.我正在使用最新版本的 Gradle (
7.3.1
),我无法重现您的确切问题。
I see at the beginning stuff like this:我在一开始看到这样的东西:
> Evaluating settings > Generating gradle-api-7.3.1.jar
> Evaluating settings > Generating gradle-kotlin-dsl-extensions-7.3.1.jar
...
So I suspect that Gradle manages to generate the kotlin dsl jars that you have issues with.所以我怀疑 Gradle 会设法生成您遇到问题的 kotlin dsl jar。
But my build is failing at:但是我的构建失败了:
FAILURE: Build failed with an exception.
* Where:
Build file '/home/work/lib/build.gradle.kts' line: 9
* What went wrong:
Plugin [id: 'org.jetbrains.kotlin.jvm', version: '1.5.31'] was not found in any of the following sources:
- Gradle Core Plugins (plugin is not in 'org.gradle' namespace)
- Plugin Repositories (could not resolve plugin artifact 'org.jetbrains.kotlin.jvm:org.jetbrains.kotlin.jvm.gradle.plugin:1.5.31')
Searched in the following repositories:
Gradle Central Plugin Repository
Which is similar to yours and makes sense to me.这与您的相似,对我来说很有意义。 Gradle can not get the plugin
Gradle 无法获取插件
So following your approach, I prepared a pom file to download all the required dependencies.因此,按照您的方法,我准备了一个pom 文件来下载所有必需的依赖项。
Then I have also an alternative maven setting file ( maven-settings.xml
) that moves the local maven repository somewhere else:然后我还有一个替代的 maven 设置文件(
maven-settings.xml
),它将本地 maven 存储库移动到其他地方:
<settings>
<localRepository>/home/work/work/repo/m2</localRepository>
</settings>
Then I run maven to download all the dependencies to my local folder:然后我运行 maven 将所有依赖项下载到我的本地文件夹:
mvn dependency:go-offline -s maven-settings.xml
Then I need to indicate to Gradle that it should consume from this local repo (see Gradle Offline Build Using Maven Repository ):然后我需要向 Gradle 表明它应该从此本地存储库中使用(请参阅Gradle Offline Build Using Maven Repository ):
In the settings.gradle.kts
file:在
settings.gradle.kts
文件中:
// Use the local maven repository:
pluginManagement {
repositories {
maven {
url = uri("file:///home/work/repo/m2")
}
}
}
In the lib/build.gradle.kts
(my Gradle project is called lib
, as generated with gradle init
), edit the repositories
bloc:在
lib/build.gradle.kts
(我的 Gradle 项目称为lib
,由gradle init
生成),编辑repositories
块:
repositories {
// Use the local maven repository:
maven {
url = uri("file:///home/work/repo/m2")
}
// Use Maven Central for resolving dependencies.
mavenCentral()
}
In theory we could even remove the mavenCentral()
line, because in a scenario where Gradle is used with the --offline
flag or without any internet connection it will not be used.理论上,我们甚至可以删除
mavenCentral()
行,因为在 Gradle 与--offline
标志一起使用或没有任何互联网连接的情况下,它将不会被使用。
Then the build is working like a charm (inside my container without internet access):然后构建就像一个魅力(在我的容器内没有互联网访问):
root@574b7fd57f6d:/home/work# ./gradlew build

This was because for the dependency org.jetbrains.kotlin:kotlin-test
you also will need the kotlin-test-1.5.31.module
file.这是因为对于依赖
org.jetbrains.kotlin:kotlin-test
,您还需要kotlin-test-1.5.31.module
文件。 See Gradle Module Metadata documentation page.请参阅Gradle 模块元数据文档页面。
This is why I have also this dependency:这就是为什么我也有这种依赖:
<dependency>
<groupId>org.jetbrains.kotlin</groupId>
<artifactId>kotlin-test</artifactId>
<version>1.5.31</version>
<type>module</type><!-- force maven to download the gradle metadata for this dependency -->
</dependency>
in the POM file that helps to collect all dependencies in advance.在有助于提前收集所有依赖项的 POM 文件中。
