maven创建简单项目
执行以下命令报错:
mvn archetype:create -DgroupId=org.infohold.stormexample -DpackageName=org.infohold.stormexample -DartifactId=simple
错误信息:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-archetype-plugin:2.4:create (default-cli) on project standalone-pom: Unable to parse configuration of mojo org.apache.maven.plugins:maven-archetype-plugin:2.4:create for parameter #: Cannot create instance of interface org.apache.maven.artifact.repository.ArtifactRepository: org.apache.maven.artifact.repository.ArtifactRepository.() -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch. [ERROR] Re-run Maven using the -X switch to enable full debug logging.
报错原因:
maven3中create命令已过时,使用generate命令代替。
mvn archetype:generate -DgroupId=org.sonatype.mavenbook.ch03 -DartifactId=simple -DpackageName=org.sonatype.mavenbook

编译: mvn package
编译后生成target目录
执行实例: java -cp target/simple-1.0-SNAPSHOT.jar org.sonatype.mavenbook.ch03.App 或 java -jar target/simple-1.0-SNAPSHOT.jar
