I want to find a maven native (i.e. without calling external programs) to inject the svn revision in the war manifest.
Does anybody know a way to do that?
I found mention to how to add the subversion revision to manifests in jar files but not with war files.
I searched SO but could not find this issue specifically.
I want to find a maven native (i.e. without calling external programs) to inject the svn revision in the war manifest.
This is possible with the Build Number Maven Plugin using the svnjava provider:
If you need to execute the plugin on
machine without any svn in the path
you can configure the mojo to use the
svnjava provider.
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>buildnumber-maven-plugin</artifactId>
<version>1.0-beta-3</version>
<executions>
<execution>
<phase>validate</phase>
<goals>
<goal>create</goal>
</goals>
</execution>
</executions>
<configuration>
<doCheck>true</doCheck>
<doUpdate>true</doUpdate>
<providerImplementations>
<svn>javasvn</svn>
</providerImplementations>
</configuration>
</plugin>
</plugins>
</build>
The Build Number Maven Plugin sets the build number in the ${buildNumber} property that you can then use in your POM.
I found mention to how to add the subversion revision to manifests in jar files but not with war files.
Then, to add the build number in the MANIFEST of a war, configure the plugin as mentioned in the Usage page:
<build>
...
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.0.2</version>
<configuration>
<archive>
<manifest>
<addDefaultImplementationEntries>true</addDefaultImplementationEntries>
</manifest>
<manifestEntries>
<Implementation-Build>${buildNumber}</Implementation-Build>
</manifestEntries>
</archive>
</configuration>
</plugin>
</plugins>
</build>
Try this. About halfway down, look for maven-war-plugin
<build>
...
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.0.2</version>
<configuration>
<archive>
<manifest>
<addDefaultImplementationEntries>true</addDefaultImplementationEntries>
</manifest>
<manifestEntries>
<Implementation-Build>${buildNumber}</Implementation-Build>
</manifestEntries>
</archive>
</configuration>
</plugin>
</plugins>
</build>

Currently I have a multi module project with maven, in the super pom I have added the modules of the projects. From the SparkAppBuilder module I intend to build the jar project that contains the SparkDriver and SparkProcess projects.
To do this from the SparkAPPBuilder module, add the maven-assembly-plugin plugin, I see that it builds the project by adding my 2 modules, but the problem is that it is generating the jar with all the dependencies that are in my local repository, so the jar weighs more than 150MB.
This is my SparkAppBuilderPOM:

Do you know why you add my entire local repository in the assmbly phase?
Thanks so much.

A jar-with-dependencies also contains all transitive dependencies. Those are usually needed to run the project because they are the dependencies of your dependencies.
So it is not unusual that this jar is large. You should look in your mvn dependency:tree where most of the stuff comes from -- then you might be able to reduce the amount by changing the dependencies of your modules.
So: The jar-with-dependencies does not contain the whole local repository, just the whole dependency tree.
I am using Maven to manage my dependencies and am trying to pull a few, proprietary, jar files from my project directory. (Yes, I know, I'm a crazy idiot who doesn't get the purpose of Maven and should never do this.) On compilation, I get the typical warnings about pointing to files in my project directory. However, the specified jar files are not placed in my .m2 directory, and thus, the project does not compile as dependencies are missing.
In pom.xml:
<dependency>
<groupId>org.sample</groupId>
<artifactId>sample</artifactId>
<scope>system</scope>
<version>2.0.3</version>
<systemPath>${project.basedir}/WebContent/WEB-INF/lib/my_file.jar</systemPath>
<type>jar</type
<optional>true</optional>
</dependency>
Question is, am I declaring my groupId and artifactId correctly? Is there a way to force Maven to use several, random, jar files in my project directory?
Thanks for the help.
You have to add the jar in your classpath as well for mvn to pickup your system dependencies.
<Class-Path>libs/my_file.jar</Class-Path>

I have an Eclipse Maven project with a Referenced Libraries folder. This folder contains the same jars that are included in project's actual classpath. To compile the project using Maven, when I use
mvn clean install
it cannot get the jars which are in classpath. So I tried using the following
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>3.0.2</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
</manifest>
<manifestEntries>
<Class-Path>.</Class-Path>
</manifestEntries>
</archive>
</configuration>
</plugin>
</plugins>
</build>
Whenever I try to compile, it gives me errors stating that it could not find the classes, those classes which I have already added on the classpath of the project.
I also tried
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>3.0.2</version>
<configuration>
<includes>
<include>/Referenced Libraries</include>
</includes>
</configuration>
</plugin>
</plugins>
</build>
but it doesn't do anything. What am I doing wrong ? How do I make the pom.xml file to get jars from the project's classpath in order to compile the project? Any help will be appreciated please. Thank You.
I'm new to maven and currently try to assemble a scala project with it. Project structure:
dir

|--src/main/java

|--src/main/scala

|--pom.xml
I was kind of surprised that classes compiled from *.java end up in jar, but one compiled from *.scala do not. I added these plugins to pom.xml

I though maven-jar-plugin is responsible for assembling jar files. But for some reason, it does not add scala-compiled classes.
QUESTION: Who adds .class file into a final jar after executing mvn install? How to add .class-files compiled with scala compiler?
mvn package will build your jar, however maven-compiler-plugin will only compile your java source files not your scala source files. Scala-maven-plugin can be used to compile both java and scala sources.
I wrote a blog post on this a while ago, that may help http://blog.rizvn.com/2016/04/scala-and-maven.html
You will need to tell maven about src/main/scala, since you are putting your scala code under src/main/java. This is done through the build section like so:
<build>
<sourceDirectory>src/main/scala</sourceDirectory>
<testSourceDirectory>src/test/scala</testSourceDirectory>
...
</build>
Can you try something like this, using "scala-maven-plugin" instead. Then execute maven goal : mvn clean package
<build>
<sourceDirectory>${basedir}/src</sourceDirectory>
<resources>
<resource>
<directory>${basedir}/src/test/resources</directory>
</resource>
</resources>

I have a java project done with Eclipse and Maven with this estructure folder:
enter image description here
Ok, when i make a Maven install to create the .jar take this structure folder:
enter image description here
So that the hierarchy is not the same and links to the images and css do not work.
I show you the code of pom.xml
enter code here

Any ideas?
thanks a lot!!

You should add a build section to your pom.xml:
<build>
<directory>${basedir}/target</directory>
<resources>
<resource>
<targetPath>${basedir}/target/resources</targetPath>
<directory>${basedir}/src/main/resources</directory>
</resource>
</resources>
</build>
Further Reference:
POM Reference (Build Section)
I think that you should create a war instead of a jar, because you are talking about css and images and jars should not contains that kind of files (see jar vs war).
In maven you only need to change the <packaging> of the project inside the POM.
