Maven: Only execute plugin when a command line flag is present

由 瘦欲@ 提交于 2019-12-01 21:20:18
问题 I want Maven to only run a certain plugin when there is a flag on the command line when I call the mvn command. for example: Let's say I have a plugin called maven-foo-plugin . I only want maven to run this plugin when the flag --foo is present when I call the maven command. So, instead of saying... mvn install ...I would say... mvn install --foo The first one should NOT use/call the plugin maven-foo-plugin , but the second one should. By default, I don't want this plugin to run, but if and

Scala, Maven, and preprocessors

由 Deadly 提交于 2019-12-01 20:52:06
问题 I know all of the philosophical arguments against preprocessors and macros in Java. I don't agree that just because some may abuse a language feature, it should be excluded for all. I would like to include __FILE__ and __LINE__ macros in my Java and Scala code for efficient logging. Any use of Exception is unacceptable because of runtime performance impacts. Those people who argue that logging can be turned off in "production code" should heed the advise of Brian Kernighan: Removing the error

Maven + Mercurial for Build Numbers

由 白昼怎懂夜的黑 提交于 2019-12-01 20:36:14
问题 I can't figure out how to get a Mercurial revision id put into my Maven build (ideally I would like it in the MANIFEST of my jars and war). The closest solution I could find is: mvn -DbuildNumber=`hg id -i` Which won't really work for Windows or my Hudson server. Luckily Hudson tags my builds but I would like some more assurance if the builds were also tagged with the Mercurial changset id. 回答1: Have a look at this previous question and the link from the accepted answer. Basically, you want

Maven: avoid deploying project package-implied artifact during standard build lifecycle

由 狂风中的少年 提交于 2019-12-01 18:56:01
问题 Is it possible to avoid deploying the artifact that is built according to the project packaging during 'deploy:deploy' processing? I mean the following: suppose we have a 'pom.xml' for web application and define packaging type as 'war' ; we want to assemble either '*.war' artifact or '*.zip' that contains our application as well as a servlet container; we want to deploy only that '*.zip' artifact during 'deploy:deploy' processing; I.e. I want to be able to run 'mvn deploy' and has the
