我有一些配置文件和各种文档,我想使用Maven2将它们从开发环境复制到dev-server目录。奇怪的是,Maven在这项任务上似乎并不强大。
以下是一些选项:
简单地使用Maven中的复制任务
< =“src /游戏/资源/文件副本配置。财产“tofile = ${项目配置}-配置服务器。财产" - >
Use the Ant plugin to execute copy from Ant.
Construct an artifact of type zip, alongside the "main" artifact of the POM which is usually of type jar, then unpack that artifact from the repository into the target directory.
maven-resources plugin, as mentioned below.
Maven Assembly plugin -- but this seems to require a lot of manual definitions, when I want to do things simply and "conventionally."
This page even shows how to build a plugin to do copying!
maven-upload plugin, as mentioned below.
maven-dependency-plugin with copy, as mentioned below.
所有这些似乎都是不必要的特别任务:Maven应该擅长于毫不费力地完成这些标准任务。
任何建议吗?
对于简单的复制任务,我可以推荐copy-rename-maven-plugin。它是直接和简单的使用:
<project>
...
<build>
<plugins>
<plugin>
<groupId>com.coderplus.maven.plugins</groupId>
<artifactId>copy-rename-maven-plugin</artifactId>
<version>1.0</version>
<executions>
<execution>
<id>copy-file</id>
<phase>generate-sources</phase>
<goals>
<goal>copy</goal>
</goals>
<configuration>
<sourceFile>src/someDirectory/test.environment.properties</sourceFile>
<destinationFile>target/someDir/environment.properties</destinationFile>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
</project>
如果你想复制多个文件,替换<sourceFile>…</destinationFile> part with
<fileSets>
<fileSet>
<sourceFile>src/someDirectory/test.environment.properties</sourceFile>
<destinationFile>target/someDir/environment.properties</destinationFile>
</fileSet>
<fileSet>
<sourceFile>src/someDirectory/test.logback.xml</sourceFile>
<destinationFile>target/someDir/logback.xml</destinationFile>
</fileSet>
</fileSets>
此外,如果需要,您可以在多个阶段指定多个执行,第二个目标是“重命名”,它只是做它所说的,而其余配置保持不变。要了解更多用法示例,请参阅用法页面。
注意:这个插件只能复制文件,不能复制目录。(感谢@james。Garriss发现了这一局限性。)
不要回避Antrun插件。仅仅因为有些人倾向于认为Ant和Maven是对立的,但事实并非如此。如果你需要执行一些不可避免的一次性定制,请使用copy任务:
<project>
[...]
<build>
<plugins>
[...]
<plugin>
<artifactId>maven-antrun-plugin</artifactId>
<executions>
<execution>
<phase>deploy</phase>
<configuration>
<target>
<!--
Place any Ant task here. You can add anything
you can add between <target> and </target> in a
build.xml.
-->
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
</plugin>
</plugins>
</build>
[...]
</project>
In answering this question, I'm focusing on the details of what you asked. How do I copy a file? The question and the variable name lead me to a larger questions like: "Is there a better way to deal with server provisioning?" Use Maven as a build system to generate deployable artifact, then perform these customizations either in separate modules or somewhere else entirely. If you shared a bit more of your build environment, there might be a better way - there are plugins to provision a number of servers. Could you attach an assembly that is unpacked in the server's root? What server are you using?
再说一次,我相信有更好的办法。
上面的蚂蚁解决方案是最容易配置的,但我有幸使用了Atlassian的maven-upload-plugin。我找不到好的文档,下面是我如何使用它:
<build>
<plugin>
<groupId>com.atlassian.maven.plugins</groupId>
<artifactId>maven-upload-plugin</artifactId>
<version>1.1</version>
<configuration>
<resourceSrc>
${project.build.directory}/${project.build.finalName}.${project.packaging}
</resourceSrc>
<resourceDest>${jboss.deployDir}</resourceDest>
<serverId>${jboss.host}</serverId>
<url>${jboss.deployUrl}</url>
</configuration>
</plugin>
</build>
像“${jboss.”上面引用的Host}定义在我的~/.m2/settings.xml中,并使用maven配置文件激活。这个解决方案并不局限于JBoss,这只是我给变量命名的方式。我有开发,测试和现场的资料。因此,要在测试环境中上传我的耳朵到jboss实例,我将执行:
mvn upload:upload -P test
下面是settings.xml的一个片段:
<server>
<id>localhost</id>
<username>username</username>
<password>{Pz+6YRsDJ8dUJD7XE8=} an encrypted password. Supported since maven 2.1</password>
</server>
...
<profiles>
<profile>
<id>dev</id>
<properties>
<jboss.host>localhost</jboss.host>
<jboss.deployDir>/opt/jboss/server/default/deploy/</jboss.deployDir>
<jboss.deployUrl>scp://root@localhost</jboss.deployUrl>
</properties>
</profile>
<profile>
<id>test</id>
<properties>
<jboss.host>testserver</jboss.host>
...
注:
有这个插件的Atlassian maven repo在这里:https://maven.atlassian.com/public/
我建议下载源代码,并查看其中的文档,以了解插件提供的所有功能。
