Gradle plugin: Duplicated tag: 'dependencyManagement'

For build.gradle, when using

    dependencies {
        constraints {
            compile("com.fasterxml.jackson.core:jackson-databind:${jacksonVersion}") {
                because 'previous versions have security issues'
            }
        }
    }

in combination with

apply plugin: 'io.spring.dependency-management'

dependencyManagement {
    imports {
        mavenBom "org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}"
    }
}

an invalid POM file is generated with two dependencyManagement elements. Deployment (artifactoryPublish) is thus refused by the artifactory server.

I had the same problem.

You don´t need to/cannot use the ‘io.spring.dependency-management’ plugin in the project where you use your bom. so no "dependencymanagement in the build gradle too!

All you need is:

dependencies {

implementation platform('your-bom:version')

//your deps

}

Had the same problem and just implemented a hack that combines the content of the two dependency management blocks.

task fixPom {
    doLast {
        File file = new File("$buildDir/publications/mavenJava/pom-default.xml")
        def text = file.text
        def pattern = "(?s)(<dependencyManagement>.+?<dependencies>)(.+?)(</dependencies>.+?</dependencyManagement>)"
        Matcher matcher = text =~ pattern
        if (matcher.find()) {
            text = text.replaceFirst(pattern, "")
            def firstDeps = matcher.group(2)
            text = text.replaceFirst(pattern, '$1$2' + firstDeps + '$3')
        }
        file.write(text)
    }
}
