使用gradle构建时读取maven settings.xml?

我有一个maven settings.xml位于:

 /home/u123/.m2/settings.xml

我指定了一个远程maven存储库:

<?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>

在这个回购中,我已经部署了一个工件 - 实际上它是一个gradle插件。

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'
    }
}

但是构建失败了:

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

Gradle无法找到my-gradle-plugin,即使我有上面的settings.xml文件指向远程maven存储库。

如果我在我的build.gradle文件中指定存储库,它可以工作:

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

似乎gradle考虑了settings.xml文件,所以出了什么问题?

有一个与此相关的开放票据有望实施:

但作为一种解决方法,您可以在build.gradle中使用一些groovy脚本来实现此目的。在我的情况下,我需要来自settings.xml的身份验证信息。但这很容易适应以获取存储库信息。

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 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"])
    }


  }
}

我使用maven-publish,maven-publish-auth插件来完成此操作而无需手动解析设置

gradle-maven-settings-plugin适合我(至少在我的Windows环境中)

应该添加

buildscript {
    repositories {
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }
}

plugins {
    id 'net.linguica.maven-settings' version '0.5'
}

build.gradle然后可以像这样添加存储库:

repositories {
    maven {
        name = 'myRepo' // should match <id>myRepo</id> of appropriate <server> in Maven's settings.xml
        url = 'https://intranet.foo.org/repo'
    }
}

将使用Maven myRepo的{​​{1}}个凭据访问https://intranet.foo.org/repo存储库

请参阅:https://github.com/ci-and-cd/maven-settings-decoder

我在gradle构建脚本中使用它以避免在build.gradle或环境变量中公开nexus密码。

buildscript {
  repositories {
    ...
    mavenCentral()
  }
  dependencies {
    ...
    classpath 'cn.home1.tools:maven-settings-decoder:1.0.5.OSS'
  }
}
...
ext.mavenSettings = new cn.home1.tools.maven.SettingsDecoder();
ext.nexusSnapshotsUser = mavenSettings.getText("//server[id='${nexus}-snapshots']/username/text()")
ext.nexusSnapshotsPass = mavenSettings.getText("//server[id='${nexus}-snapshots']/password/text()")
println "${nexus}-snapshots username: " + mavenSettings.getText("//server[id='${nexus}-snapshots']/username/text()")
println "${nexus}-snapshots password: " + mavenSettings.getText("//server[id='${nexus}-snapshots']/password/text()")
...

请在build.gradle文件的存储库部分中使用mavenLocal()。这应该在您的主目录中读取〜/ .m2 / settings.xml文件。

repositories {
    mavenCentral()
    mavenLocal()
}
