Converting settings.xml and pom.xml from Maven to build.gradle in Gradle involves translating Maven's repository settings, profiles, mirrors, and authentication details into Gradle's DSL for java application. Here’s how to do it step by step:
1. Identify Relevant Sections in settings.xml
Maven’s settings.xml typically contains:
- Repositories
(central, mirrors, etc.)
- Authentication
credentials (server credentials)
- Profiles
(used to define custom build configurations)
- Active
profiles (which profile is in use)
Profiles
Gradle uses properties instead of profiles. Convert
Maven profiles into Gradle properties:
|
ext { isCustomProfileEnabled =
project.hasProperty('customProfile') } repositories
{ if (isCustomProfileEnabled) { maven { url
"https://your.company.com/repository/maven-releases/" } } } |
Final Thoughts
- Repositories:
Move <repositories> and <mirrors> into Gradle’s repositories
block.
- Authentication:
Use credentials {} inside maven {} and avoid hardcoding passwords.
- Profiles:
Use Gradle properties (-PprofileName) instead of Maven <profiles>.
- Global
Configuration: Use an init.gradle file if you need settings for
multiple projects.
1. Identify Key Sections in pom.xml
Your pom.xml includes:
- Basic
project metadata (groupId, artifactId, version)
- Properties
(JDK version, dependencies versions, encoding, etc.)
- Build
plugins (not listed yet but will be needed)
|
Maven (pom.xml) |
Gradle (build.gradle) |
|
<groupId>com.kartik.1kcm</groupId> |
group = 'com.kartik.1kcm' |
|
<artifactId>KartikInterface</artifactId> |
artifactId is not explicitly needed in Gradle.
This is declare in settings.gradle file rootProject.name=KartikInterface |
|
<version>${revision}</version> |
version = project.findProperty('revision') ?:
'1.0.1-SNAPSHOT' |
|
<properties> |
Converted to Gradle
properties (project.findProperty('propertyName')) |
|
<jdk.version>17</jdk.version> |
sourceCompatibility = JavaVersion.VERSION_17 |
|
<maven.compiler.source>17</maven.compiler.source> |
sourceCompatibility = JavaVersion.VERSION_17 |
|
<maven.compiler.target>17</maven.compiler.target> |
targetCompatibility = JavaVersion.VERSION_17 |
|
<revision>1.0.1-SNAPSHOT</revision> |
Handled via project.findProperty('revision') |
|
<commons-cli-version>1.3.1</commons-cli-version> |
Used in dependencies section |
|
<skipTests>true</skipTests> |
tasks.withType(Test) { enabled = false } |
|
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> |
options.encoding = 'UTF-8' |
