How to make gradle generate a valid pom.xml file at the root of a project for maven users?
Solution 1:
You can use the gradle maven plugin. This adds the pom
convention method to your project, which you can use in a task to generate a pom.xml
file, like
task writeNewPom {
doLast {
pom {
project {
groupId 'org.example'
artifactId 'test'
version '1.0.0'
inceptionYear '2008'
licenses {
license {
name 'The Apache Software License, Version 2.0'
url 'http://www.apache.org/licenses/LICENSE-2.0.txt'
distribution 'repo'
}
}
}
}.writeTo("pom.xml")
}
}
Then you call gradle createPom
to generate the pom.xml in the project root. Of all the things in the pom definition, you should really provide groupId
, artifactId
and version
, other thins like licenses
are not that important.
You can also look at this example for a project definition with some dependencies, and try running it to see what it produces.
Some of the new keywords were added and some techniques were deprecated. Please check
Solution 2:
Here is my build.gradle
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'maven'
repositories {
mavenLocal()
mavenCentral()
}
dependencies {
compile 'org.springframework:spring-core:4.0.5.RELEASE'
compile 'org.springframework:spring-webmvc:4.0.5.RELEASE'
compile 'org.slf4j:slf4j-api:1.7.5'
runtime 'org.slf4j:slf4j-log4j12:1.7.5'
testCompile 'org.springframework:spring-test:4.0.5.RELEASE'
testCompile 'junit:junit:4.11'
testCompile "org.mockito:mockito-core:1.9.5"
testCompile "org.hamcrest:hamcrest-library:1.3"
testCompile 'javax.servlet:javax.servlet-api:3.0.1'
}
test {
testLogging {
// Show that tests are run in the command-line output
events 'started', 'passed'
}
}
task wrapper(type: Wrapper) { gradleVersion = '1.12' }
task createPom {
pom {
project {
groupId 'sg.test.spring.web.guide'
artifactId 'sg-web-initial'
version '1.0.0-SNAPSHOT'
inceptionYear '2008'
licenses {
license {
name 'The Apache Software License, Version 2.0'
url 'http://www.apache.org/licenses/LICENSE-2.0.txt'
distribution 'repo'
}
}
}
}.writeTo("pom.xml")
}
You can name the task createPom
to anyTaskName
as you like.
Then just run gradle clean
or grale build
or simply gradle createPom
.
This will generate it as pom.xml in the root of the project. Although you can replace writeTo("pom.xml")
with writeTo("<anyDir>/newpom.xml")
.
The resulting pom.xml:
<?xml version="1.0" encoding="UTF-8"?>
