I'm trying to build a jar file using 2 different source directories. So I'm using the maven-compiler-plugin. Here is my config:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<includes>
<include>**/*</include>
<include>src/main/java/**/*.java</include>
<include>../syncrpc/src/main/java/**/*.java</include>
</includes>
</configuration>
</plugin>
It builds alright but my jar file is empty (almost)... and my usual "target/classes" dir is empty. I suppose by default the compiler creates this directory and puts all the packages with the built classes. Can I do manually when I use the maven-compiler-plugin?
Thank you
Found a solution:
build-helper-maven-plugin
Basically, use the helper plugin instead, and it works perfectly.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<executions>
<execution>
<phase>generate-sources</phase>
<goals><goal>add-source</goal></goals>
<configuration>
<sources>
<source>../syncrpc/src/main/java/com/gdevelop/gwt/syncrpc</source>
</sources>
</configuration>
</execution>
</executions>
</plugin>

I have the need to create a deployable ZIP archive from a script, much as the "Export" function does in Mule Studio. I'm expecting the ZIP to contain everything needed to deploy the app: JAR files, message flows, etc etc etc - again, just as Mule Studio Export does.
Is there a simple way to do this, or an example I can follow?
Maven is your best bet. Using the mule plugin for maven runnning mvn package will produce the deployable archive. More info on Mule and Maven here: http://www.mulesoft.org/documentation/display/current/Using+Maven+with+Mule
There is also an ant plugin but don't use it myself. Some info here: http://blogs.mulesoft.org/building-mule-apps-with-ant/
Alternatively, you can read about the application deployment structure here: http://www.mulesoft.org/documentation/display/current/Application+Format , so in theory you can build this structure yourself. But I wouldn't advise it and would stick to Maven.
Use Maven for building the app in jar/zip and deploy to the Mule standalone server automatically ... Make Sure your MULE_HOME is set to your standalone server in Environment variable ... and insert the following in your Maven Script to build it in Jar/Zip and deploy to app folder of Mule Standalone directly :-
<build>
<resources>
<resource>
<directory>>${project.basedir}/lib</directory>

I have :
src/main/java/com.tuto
Class1.java
Class2.java
Class3.java
My pom is packaging a war.
So in my war, in WEB-INF/classes/com/tuto I found the 3 classes.
Now I want to exclude Class2.java
I tried
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.1</version>
<configuration>
<excludes>
<exclude>**/Class2.class</exclude>
</excludes>
</configuration>
</plugin>
But it's not working.
How can I do ?
Ok, so like Aaron tell me, this is working :
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.1</version>
<configuration>
<packagingExcludes>**/Class2.class</packagingExcludes>
</configuration>
</plugin>
But ...
Let's take the problem by the other side : I want to exclude all except Class1 and Class3
So I tried
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.1</version>
<configuration>
<packagingIncludes>**/Class1.class,**/Class3.class</packagingIncludes>
</configuration>
</plugin>
and this time it's not working.
As the documentation says, you should use the packagingExcludes element instead.
Note that packagingExcludes doesn't use nested elements. Instead, the content is a "comma-separated list of Ant file set patterns".
From the documentation, excludes will take higher priority over includes. In your case, use packagingExcludes for excluding class2 explicitly.
<packagingExcludes>WEB-INF/classes/com/tuto/Class2.class</packagingExcludes>
The complete plugin xml should be like the following
<plugin>
<artifactId>maven-war-plugin</artifactId>
<configuration>
<outputDirectory>${build.output.directory}</outputDirectory>
<packagingExcludes>WEB-INF/classes/ItemConsumer.class</packagingExcludes>
</configuration>
</plugin>
add plugin to pom.xml - 100% working properly.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.3</version>
<configuration>

I am using maven-compile plugin to compile classes. Now I would like to add one jar file into the current classpath. That file stays in another location (let's say c:/jars/abc.jar . I prefer to leave this file here). How can I do that?
If I use classpath in the argument:
<configuration>
<compilerArguments>
<classpath>c:/jars/abc.jar</classpath>
</compilerArguments>
</configuration>
it will not work because it will override the current classpath (that includes all the dependencies)
This might have been asked before. See Can I add jars to maven 2 build classpath without installing them?
In a nutshell: include your jar as dependency with system scope. This requires specifying the absolute path to the jar.
See also http://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html
The classpath setting of the compiler plugin are two args. Changed it like this and it worked for me:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.6.1</version>
<configuration>
<compilerArgs>
<arg>-cp</arg>
<arg>${cp}:${basedir}/lib/bad.jar</arg>
</compilerArgs>
</configuration>
</plugin>
I used the gmavenplus-plugin to read the path and create the property 'cp':
<plugin>
<!--
Use Groovy to read classpath and store into
file named value of property <cpfile>
In second step use Groovy to read the contents of
the file into a new property named <cp>
In the compiler plugin this is used to create a
valid classpath
-->

<artifactId>gmavenplus-plugin</artifactId>
<version>1.12.0</version>
<dependencies>
<dependency>
<groupId>org.codehaus.groovy</groupId>
<artifactId>groovy-all</artifactId>
<!-- any version of Groovy \>= 1.5.0 should work here -->
<version>3.0.6</version>
<type>pom</type>
<scope>runtime</scope>
</dependency>

</goals>
</execution>
</executions>
<configuration>
<scripts>
<script><![CDATA[
def file = new File(project.properties.cpfile)
/* create a new property named 'cp'*/
project.properties.cp = file.getText()
println '<<< Retrieving classpath into new property named <cp> >>>'
println 'cp = ' + project.properties.cp
]]></script>
</scripts>
</configuration>
</plugin>
From docs and example it is not clear that classpath manipulation is not allowed.
<configuration>
<compilerArgs>
<arg>classpath=${basedir}/lib/bad.jar</arg>
</compilerArgs>
</configuration>
But see Java docs (also https://www.cis.upenn.edu/~bcpierce/courses/629/jdkdocs/tooldocs/solaris/javac.html)
-classpath path Specifies the path javac uses to look up classes needed to run javac or being referenced by other classes you are
compiling. Overrides the default or the CLASSPATH environment variable
if it is set.
Maybe it is possible to get current classpath and extend it,
see in maven, how output the classpath being used?

We mixed two of the answers found here to solve a similar problem. Our project needs a JAR only in compile stage, but add a local dependency, using system scope, it is unuseful because Maven refuse the artifact publication with an error related to a missing dependency.
The snippets used are the following:
<properties>
<classpathfile>${basedir}/classpathfile.classpath</classpathfile>
</properties>

Maven is able to compile and successfully deploy the artifacts.
If anyone is interested the full POM is available in GitHub under project NuReflector, defaultPOM.template under src/NuReflector.
I'm trying to get Maven to perform several executions with the WAR plugin. It works fine as long as it's defined in the following way:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>1.0</version>
<configuration>
(...)
</configuration>
But not in the following manner
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>1.0</version>
<executions>
<execution>
<phase>package</phase>
<configuration>
(...)
</configuration>
</execution>
</executions>
</plugin>
Where Maven can't find any of the resources I defined in the <configuration> tag. Have I missed anything important, and/or is there a better way of constructing multiple WAR files in a single build?
I didn't see how to turn off the war that's generated by default, but you can use one configuration outside the <executions> element and the rest inside:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.1-beta-1</version>
<configuration>
<classifier>with-junk</classifier>
<!-- temp directory that the webapp is assembled in (each must be different) -->
<webappDirectory>${project.build.directory}/build-with-junk</webappDirectory>
<webResources>
<resource>
<directory>junk</directory>
<includes>
<include>**/*</include>
</includes>
</resource>
</webResources>
</configuration>
<executions>
<execution>
<id>add-other-junk</id>
<phase>package</phase>
<goals>
<goal>war</goal>
</goals>
<!-- exclude prior configuration -->
<inherited>false</inherited>
<configuration>
<classifier>with-other-junk</classifier>
<webappDirectory>${project.build.directory}/build-other-junk</webappDirectory>
<webResources>
<resource>
<directory>other-junk</directory>
<includes>
<include>**/*</include>
</includes>
</resource>
</webResources>
</configuration>
</execution>
</executions>
</plugin>
For me, this builds artifact-0.1-with-junk.war and artifact-0.1-with-other-junk.war and both have the correct files included.
The second version applies the configuration only to the phase you've specified. I'm not able to confirm this right now, but I'd guess it is not being applied because you haven't specified a goal for the configuration to be applied to.
If you add the war goal definition into the execution does it get applied? Like so:
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>war</goal>
</goals>
<configuration>
(...)
</configuration>
</execution>
</executions>
I managed to create main jar, copy dependencies to a single directory, the only step left is to sign all jars.
I can sign my own produced jar as a part of jar:sign, but how do i sign dependencies?
Thanks
Here are a couple of options:
Use the Maven ant task to run jarsigner from the JDK against all the dependencies.
Use the webstart plugin which can sign all your JARs, even if you aren't using it for the purpose of JNLP-izing your app. I'm using it to actually JNLPize one app.
Look at what the webstart plugin source is doing to iterate over all dependencies and sign them and start a new Maven Plugin/Mojo that does the same thing, sans JNLP.
Onejar your app and its dependencies and just sign that.
add to plug-in config <archiveDirectory>target</archiveDirectory>
If you are using maven-jar-plugin, you can specify which single jar to sign using the "jarPath" setting. The following configuration causes the jar-with-dependencies file to be signed instead of the dependency-less jar file:
<plugin>
<artifactId>maven-jar-plugin</artifactId>
<executions>
<execution>
<goals>
<goal>sign</goal>
</goals>
</execution>
<execution>
<id>make-assembly</id>
<phase>package</phase>
<goals>
<goal>sign</goal>
</goals>
</execution>
</executions>
<configuration>
<!-- NOTE: The secret key is in shared version control. The
password is in shared version control. This IS NOT
SECURE. It's intended to help avoid accidentally
loading the wrong class, nothing more. -->
<jarPath>${project.build.directory}/${project.build.FinalName}-${project.packaging}-with-dependencies.${project.packaging}</jarPath>
<keystore>${basedir}/keystore</keystore>
<alias>SharedSecret</alias>
<storepass>FOO</storepass>
</configuration>
</plugin>
If you want to sign both, I don't know how to do that with maven-jar-plugin, so you may need to look into the other options mentioned above.
One can also create a single JAR using the maven-assembly-plugin.
Together with the other suggestion by Eric Anderson (of signing another JAR) one can then sign this assembled JAR (instead of the original JAR). Note that the order of the plugin definitions matters here.
It is assumed that sign.keystore.file etc are set elsewhere (e.g. in a profile).
