The other thing that could be going wrong is that your machine is behind a firewall or proxy so your box is not able to hit http://repo1.maven.org/maven2. Try accessing this URL directly in a browser or something to test if you are able to make the request.
Both of your solutions wouldn’t help, as they would add an additional resource that is then deactivated. The webapp source folder is copied by default, without the resource mechanism. The mechanism to deactivate a part of that is through the <warSourceExcludes> parameter, like this: <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-war-plugin</artifactId> <version>2.1</version> <configuration> <warSourceExcludes>webscripts/**</warSourceExcludes> </configuration> </plugin>
Where is the best place to specify required repositories for maven projects, pom.xml or settings.xml? What are the pros and cons of each location? What is best practice? I’d personally define the repositories required by a particular project in the project pom.xml because it keeps the build portable. The settings.xml file should be used for … Read more
If the file is a Maven dependency, you could use the Maven Dependency Plugin which has a get goal. For any file, you could use the Antrun plugin to call Ant’s Get task. Another option would be the maven-download-plugin, it has been precisely created to facilitate this kind of things. It’s not very actively developed … Read more
Overriding configurations from a parent pom can be done by adding the combine.self=”override” attribute to the element in your pom. Try changing your plugin configuration to: <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <executions> <execution> <id>my-testCompile</id> <phase>test-compile</phase> <goals> <goal>testCompile</goal> </goals> <configuration combine.self=”override”> <fork>true</fork> <executable>${jdk15.executable}</executable> <compilerVersion>1.5</compilerVersion> <source>1.5</source> <target>1.5</target> <verbose>true</verbose> </configuration> </execution> </executions> </plugin> For more information on overriding plugins, see: … Read more
Maven 3 (as of beta 1) now supports parallel builds as an experimental feature. For example, mvn -T 4 clean install # Builds with 4 threads mvn -T 1C clean install # 1 thread per cpu core mvn -T 1.5C clean install # 1.5 thread per cpu core Full documentation can be found on the … Read more
Ken, good question. I should be more explicit in the The Definitive Guide about the difference. “install” and “deploy” serve two different purposes in a build. “install” refers to the process of installing an artifact in your local repository. “deploy” refers to the process of deploying an artifact to a remote repository. Example: When I … Read more
Let me extend Sean’s answer. This is what you set in pom.xml: <properties> <exclude.tests>nothing-to-exclude</exclude.tests> </properties> <profiles> <profile> <id>fast</id> <properties> <exclude.tests>**/*Dao*.java</exclude.tests> </properties> </profile> </profiles> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <configuration> <excludes> <exclude>${exclude.tests}</exclude> </excludes> </configuration> </plugin> Then in CI you start them like this: mvn -Pfast test That’s it.
on command line -DoutputDirectory=<path> and in pom.xml <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-jar-plugin</artifactId> <version>2.3.1</version> <configuration> <outputDirectory>/my/path</outputDirectory> </configuration> </plugin> </plugins> </build>
On the CLI, use mvn dependency:tree (Here are some additional Usage notes) When running dependency:tree on multi-module maven project, use mvn compile dependency:tree instead1. Otherwise, the POM Editor in M2Eclipse (Maven integration for Eclipse) is very good, and it includes a hierarchical dependency view. 1If you don’t compile, you might get error Failed to execute … Read more
