使用gradle构建时读取maven settings.xml？ [英] Reading a maven settings.xml when building with gradle?

问题描述

我有一个maven settings.xml位于：

  /home/u123/.m2/settings.xml 
  

其中我指定了一个远程Maven仓库：

 <？xml version =1.0encoding =UTF-8？> 
< settings> 
<个人资料> 
<个人资料> 
< id>预设< / id> 
< repositories> 
< repository> 
< id> my.repo< / id> 
< url> http：// myrepo /< / url> 
< / repository> 
< / repositories> 
< / profile> 
< / profiles> 
< activeProfiles> 
< activeProfile>预设< / activeProfile> 
< / activeProfiles> 
< / settings> 
  

在这个回购中，我部署了一个工件 - 实际上它是一个gradle插件。
$ b

现在我尝试使用下面的build.gradle文件构建另一个需要使用此插件/工件的项目：

  apply plugin：'java'
 apply plugin：'maven'
 
 buildscript {
 dependencies {
 classpath 'com.test：my-gradle-plugin：1.0.0-SNAPSHOT'
} 
} 
  

但构建失败：

  ... 
>找不到组：com.test，模块：my-gradle-plugin，版本：1.0.0-SNAPSHOT。 
 ... 
  

Gradle无法找到我的gradle插件，即使我有上述settings.xml文件指向远程maven仓库。

如果我在我的build.gradle文件中指定存储库，它可以工作： p>

  buildscript {
 repositories {
 maven {
 urlhttp ：// myrepo /
} 
} 
依赖关系{
 classpath'com.test：my-gradle-plugin：1.0.0-SNAPSHOT'
} 
 
  

基于这篇文章：

似乎gradle认为settings.xml文件出了什么问题？

解决方案

有一个操作与此相关的票将有望实施：

http://issues.gradle.org/browse/GRADLE-2365

但是作为一种解决方法，您可以在构建中使用一些groovy脚本.gradle来实现这一点。在我的情况下，我需要settings.xml中的认证信息。

示例：

  def getMavenSettingsCredentials = {
 String userHome = System.getProperty（user.home）; 
 File mavenSettings = new File（userHome，.m2 / settings.xml）
 def xmlSlurper = new XmlSlurper（）
 def output = xmlSlurper.parse（mavenSettings）
 return输出。servers。server
} 
 
 def getCredentials = {
 def entries = getMavenSettingsCredentials（）
（条目中的条目）{
）if（entry。id.text（）==my-server）{
 return [username：entry.username.text（），password：entry.password.text（）] 
} 
} 
} 
 uploadArchives {
 def creds = getCredentials（）
 repositories.mavenDeployer {
 configuration = configurations.deployerJars 
 repository （url：http：// my-release-repository / releases /）{
 authentication（userName：creds [username]，password：creds [password]）
} 
 snapshotRepository（url：http：// my-snapshot-repository / snapshots /）{
 authentication（userName：creds [username]，password：creds [password]）
 } 
 
 
} 
} 
  

I have a maven settings.xml located in:

 /home/u123/.m2/settings.xml

where I specify a remote maven repository:

<?xml version="1.0" encoding="UTF-8"?>
<settings>
  <profiles>
    <profile>
      <id>default</id>
      <repositories>
          <repository>
              <id>my.repo</id>
               <url>http://myrepo/ </url>
          </repository>
      </repositories>
    </profile>
  </profiles>
  <activeProfiles>
    <activeProfile>default</activeProfile>
  </activeProfiles>
</settings>

In this repo I have deployed an artifact - actually its a gradle plugin.

Now I try to build another project that needs to use this plugin/artifact using the below build.gradle file:

apply plugin: 'java'
apply plugin: 'maven'

buildscript {
    dependencies {
        classpath 'com.test:my-gradle-plugin:1.0.0-SNAPSHOT'
    }
}

But the build fails:

...
> Could not find group:com.test, module:my-gradle-plugin, version:1.0.0-SNAPSHOT.
...

Gradle cannot find my-gradle-plugin even though I have the above settings.xml file pointing to the remote maven repository.

If I instead specify the repository inside my build.gradle file it works:

buildscript {
    repositories {
        maven {
            url "http://myrepo/"
        }
    }
    dependencies {
        classpath 'com.test:my-gradle-plugin:1.0.0-SNAPSHOT'
    }
}

Based on this post:

http://forums.gradle.org/gradle/topics/have_mavenlocal_check_m2_home_conf_settings_xml

it seems that gradle considers the settings.xml file so what is wrong?

解决方案

There is an open ticket related to this that will be hopefully implemented:

http://issues.gradle.org/browse/GRADLE-2365

But as a workaround you can use some groovy scripting in the build.gradle to achieve this. In my case I needed the authentication information from settings.xml. But this could easily be adapted to get repository info.

Example:

def getMavenSettingsCredentials = {
    String userHome = System.getProperty( "user.home" );
    File mavenSettings = new File(userHome, ".m2/settings.xml")
    def xmlSlurper = new XmlSlurper()
    def output = xmlSlurper.parse(mavenSettings)
    return output."servers"."server"
}

def getCredentials = {
    def entries = getMavenSettingsCredentials()
    for (entry in entries) {
        if ( entry."id".text() == "my-server" ) {
            return [username: entry.username.text(), password: entry.password.text()]
    }
  }
}
uploadArchives {
def creds = getCredentials()
repositories.mavenDeployer {
    configuration = configurations.deployerJars
    repository(url: "http://my-release-repository/releases/") {
        authentication(userName: creds["username"], password: creds["password"])
    }
    snapshotRepository(url: "http://my-snapshot-repository/snapshots/") {
        authentication(userName: creds["username"], password: creds["password"])
    }


  }
}
