10. Maven Artifacts Uploader
------------------------------------------------------------------
This is a friendly command line tool for uploading a directory of artifacts to Nexus 3.x repository
1) Installation
● Clone package
git clone https://github.com/ronbadur/maven-artifacts-uploader.git
cd maven-artifacts-uploader
mvn install
● conf/config.properties
=> repository url, repositroy id
● PATH enviroment
echo "export MVN-UPLOAD=/opt/maven-artifacts-uploader" >> ~/.bashrc
echo "PATH=$PATH:$MVN-UPLOAD/bin:$HOME/bin" >> ~/.bashrc
echo "export PATH" >> ~/.bashrc
● settings.xml
<servers>
<server>
<id>nexus</id>
<username>admin</username>
<password>admin123</password>
</server>
</servers>
2) upload all the artifacts in specific directory
#mvnUploader -d path/to/your/artifacts
java -jar ./lib\nexus-uploader.jar -d /opt/mvn-repo
# To get all the options that available
mvnUploader -h
11. upload files into Nexus 3
------------------------------------------------------------------
curl -v -u admin:admin123 --upload-file pom.xml http://localhost:8081/repository/maven-releases/org/foo/1.0/foo-1.0.pom
# Example without a pom file
mvn deploy:deploy-file -DgroupId=com.somecompany -DartifactId=project -Dversion=1.0.0 -DgeneratePom=true -Dpackaging=jar -DrepositoryId=nexus -Durl=http://localhost:8081/repository/maven-releases -Dfile=target/project-1.0.0.jar
# With a pom file
mvn deploy:deploy-file -DgeneratePom=false -DrepositoryId=nexus -Durl=http://localhost:8081/repository/maven-releases -DpomFile=pom.xml -Dfile=target/project-1.0.0.jar
12. Gradle을 이용한 Nexus 저장소 Upload
------------------------------------------------------------------
Nexus 배포를 위한 uploadArchives 스크립트를 작성
# vi build.gradle
|
apply plugin: 'maven'
group = "paas.test" version = '0.0.1-SNAPSHOT'
project.group = 'paas.test'
uploadArchives { repositories { mavenDeployer { repository(url: 'http://your.nexus.repository.com/nexus/content/repositories/releases/') { authentication(userName: '계정명', password: '비밀번호') } snapshotRepository(url: 'http://your.nexus.repository.com/nexus/content/repositories/snapshot/') { authentication(userName: '계정명', password: '비밀번호') } } } } |
=> eclipse에서 uploadArchives를 실행하여 Nexus에 업로드
