问题 I have a profile in my pom.xml which should be always active unless it is explicitely deactivated (-P !firstProfile). I solved this by using the activeByDefault flag: <profiles> <profile> <id>firstProfile</id> <activation> <activeByDefault>true</activeByDefault> </activation> ... </profile> </profiles> Now in the same pom.xml I have a second profile defined this should only be active if the profile is really activated (-P secondProfile). So the default behaviour is: firstProfile active,

问题 I have a Java project that I build using an Ant script. I am trying to convert the project to Maven. One of the tasks generates a Java source file called Version.java that contains a static String representation of the compilation timestamp, as follows: package com.foo.bar; public final class Version { public static String VERSION="100301.1046"; } The Ant task is very simple: <target name="version" depends="init" description="Create Version.java"> <echo file="src/${package.dir}/Version.java"

问题 I use Eclipse, Maven, and Java in my development. I use Maven to download dependencies (jar files and javadoc when available) and Maven's eclipse plug-in to generate the .project and .classpath files for Eclipse. When the dependency downloaded does not have attached javadoc I manually add a link for the javadoc in the .classpath file so that I can see the javadoc for the dependency in Eclipse. Then when I run Maven's eclipse plugin to regenerate the .classpath file it of course wipes out that

问题 My team uses an internal team maven repo that is shared from a development server using Apache. We also run the Continuum CI server on the same machine. Maven builds in Continuum are run with the "install" goal, which copies the final artifact directly into the shared directory. The question is, what is the difference between adding files to the shared repo using mvn install and using the deploy goal (mvn-deploy plugin)? It seems to me that using mvn deploy creates additional configuration

问题 I would like to take advantage of the features that Maven provides for managing dependencies in a project. My brief understanding of how Maven works is that it will aquire the JARs needed and then build the project with these libraries. Currently I have a simple POM file set up as a test: <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

问题 How do I use maven command line to determine which settings.xml file Maven is picking up? 回答1: Start maven with -X option (debug) and examine the beginning of the output. There should be something like this: ... [INFO] Error stacktraces are turned on. [DEBUG] Reading global settings from c:\....\apache-maven-3.0.3\conf\settings.xml [DEBUG] Reading user settings from c:\....\.m2\settings.xml [DEBUG] Using local repository at C:\....\repository ... (Original directory names are removed by me)

问题 I have the following dependency in maven <dependency> <groupId>org.hyperic</groupId> <artifactId>sigar-dist</artifactId> <version>1.6.5.132</version> <type>zip</type> </dependency> This creates sigar-dist-1.6.5.132.zip in my repository. I have seen this question here, however I still can't make it work. How can I unzip the sigar-dist.zip and place the content in a directory in my project? What is the mvn call I have to do to make it work? 回答1: You can do it with dependencies:unpack
