Referencing Maven project properties of List type

//@todo

This syntax works within pom.xml and Ant build files using Maven Ant plugin. But this doesn't working with resource filtering of Maven. I can't find any explain or reason for this. Is it a bug? 

    ...
    <artifact:pom id="this-pom" file="${basedir}/pom.xml"/>
    <xsddoc out="${this-pom.reporting.outputDirectory}/xsddocs"
       verbose="true">
       <fileset dir="${this-pom.build.resources[0].directory}" 
          includes="**/*.xsd"/>
    </xsddoc>
    ...

Build Lifecycle, Build Phase, Plugin and Goal

Maven-buildlifecycle


Guidelines for multi-moduled Maven project

  1. Separate parent project from container project.
  2. Define properties in the parent POM file as possible.
  3. Define the following properties explicitly for clearness and control.
    • Encoding related properties whose default value are dependent on platform.
      • project.build.sourceEncoding
      • project.reporting.outputEncoding
    • Properties to skip situationally unnecessary long running goals.
      • skipTests
      • maven.javadoc.skip
      • maven.deploy.skip
      • findbugs.skip
      • checkstyle.skip
    • Properties to run maven more stable way.
    • Paths for executable programs external to Maven
      • graphviz.home
  1. Define all plugins in the <pluginManagement> element of parent POM file.
    • Don't specify version to plugin definitions in child POM files.
  1. Define repositories in the parent POM file as possible.
  2. Define plugins to analyze or diagnose the sources or resources of the project as a reporting plugin as possible.
  3. Start values for path with ${project.basedir}, ${project.build.directory}, ${project.build.outputDirectory} or so on
    • When just specifying relative path such as 'target/classes', the result directory could be different if you build the project from the enclosing project in multi-module case.
    • If you specify the path with leading ${project.build.directory}, the resulting directory always would be one that is calculated with the current POM's project.
  1. Use resources in target/classes not in src/main/resources, considering resource filtering.

Dependency on local library not in Maven repository and with no POM file

Sometimes your project may have dependency on a JAR file that is not registered to any of Maven repositories and so have no it's own POM file. In this case, you can use <systemPath> element to specify your module's dependency on it. 

<dependencies>
  ...
  <dependency>
    <groupId>unknown</groupId>
    <artifactId>abcd</artifactId>
    <version>1.0</version>
    <type>jar</type>
    <scope>system</scope>
    <systemPath>${project.basedir}/lib/abcd.jar</systemPath>
  </dependency>
  ...
</dependencies>

Note that systemPath could be specified only with system scope. You should specify groupId, artifactId, and version 'cause they are mandatory but you can specify any value and don't need pom file.

Escaping expression interpolation

It may necessary not to interpolate Maven expression in resources. In other words, you just want to leave ${some-property} as it is. For this, you can specify the escape string with escapeString parameter of maven-resource-plugin. You can also define maven.resources.escapeString property in your POM file.

For more refer this page : http://maven.apache.org/plugins/maven-resources-plugin/resources-mojo.html#escapeString

Working with Subversion working copy in format of ver. 1.7

The default configuration of Maven release plugin(maven-release-plugin) up to ver. 2.2.2 or Maven scm plugin(maven-scm-plugin) up to ver. 1.6 can't work correctly with Subversion working copy in format of ver. 1.7.
To solve this problem, you should override the configuration of release plugin or scm plugin to use maven-scm-provider-svnjava and svnkit 1.7. 

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-release-plugin</artifactId>
   <version>2.2.2</version>
   <configuration>
      <providerImplementations>
         <svn>javasvn</svn>
      </providerImplementations>
   </configuration>
   <dependencies>
      <dependency>
         <groupId>com.google.code.maven-scm-provider-svnjava</groupId>
         <artifactId>maven-scm-provider-svnjava</artifactId>
         <version>1.15</version>
      </dependency>
      <dependency>
         <groupId>org.tmatesoft.svnkit</groupId>
         <artifactId>svnkit</artifactId>
         <version>1.7.0-SNAPSHOT</version>
      </dependency>                
   </dependencies>
</plugin>
<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-scm-plugin</artifactId>
   <version>1.6</version>
   <configuration>
      <providerImplementations>
         <svn>javasvn</svn>
      </providerImplementations>
   </configuration>
   <dependencies>
      <dependency>
         <groupId>com.google.code.maven-scm-provider-svnjava</groupId>
         <artifactId>maven-scm-provider-svnjava</artifactId>
         <version>1.15</version>
      </dependency>
      <dependency>
         <groupId>org.tmatesoft.svnkit</groupId>
         <artifactId>svnkit</artifactId>
         <version>1.7.0-SNAPSHOT</version>
      </dependency>                
   </dependencies>
</plugin>

For now, svnkit 1.7 has no release and is in snapshot version.

If you let the plugins use svnkit 1.3.x which is default setting as of now, you would meet the exceptions like the following. 

Caused by: org.apache.maven.shared.release.scm.ReleaseScmCommandException: Unable to commit files
Provider message:
SVN commit failed.
Command output:

Release process

  • overall process
    • prepare-with-pom in dry mode > rollback > prepare > perform


  1. Check whether the free space in file system is enough for the relative servers.
    • server hosting source repository
    • server hosting binary repository
    • server hosting site documentation
  2. Synchronize all project in trunk.
  3. Run release:prepare-with-pom goal in dryRun mode with following options.
    • maven.deploy.skip = false
    • resume = false
    • dryRun = true
    • maven.home = ${env_var:MAVEN_HOME}
  4. Review pom.xml.tag, pom.xml.next, release-pom.xml in each project
    • pom.xml.tag ...
    • pom.xml.next ...
    • release-pom.xml ...
    • fully explicit(with no placeholder) scm information would exist only in pom.xml.tag file of aggregation project and parent project. Url of the scm should end with the name of the project.
  5. Run release:rollback goal with following options.
    • maven.deploy.skip = false
    • resume = false
    • maven.home = ${env_var:MAVEN_HOME}
  6. Check that all pom.xml.tag, pom.xml.next, pom.xml.backup files are deleted.
  7. Run release:prepare goal with following options
    • maven.deploy.skip = false
    • resume = false
    • maven.home = ${env_var:MAVEN_HOME}
  8. Check the new directory for the version and directories for projects under tag directory in source repository.
  9. Run release:perform goal with following options.
    • maven.deploy.skip = false
    • resume = false
    • maven.home = ${env_var:MAVEN_HOME}
  10. Refresh(F5) all projects in Eclipse.
  11. Login on binary repository and check the binaries for projects are uploaded.
  12. Test on the new version

Download a specific artifact using mvn command

You can execute dependency plugin even without a pom.xml to download a specific artifact. Note that dependency plugin needs artifact and repoUrl properties specified explicitly. 

# mvn org.apache.maven.plugins:maven-dependency-plugin:2.9:get -Dartifact=org.aspectj:aspectjweaver:1.8.1 -DremoteRepositories=central2::::http://repo2.maven.org/maven2/ -Dtransitive=false -Ddest=.

Simple tips and troubleshooting

  • The value of Maven property "project.build.directory" in normal case is ${basedir}/target. You can confirm this using the following command line : "mvn help:evaluate -Dexpression=project.build.directory".
  • Solving "[ERROR Unable to determine if resource ... exists in .." error.]
    Or just add <dependency.locations.enabled>false</dependency.locations.enabled> into the <properties> element of POM file.
