JavaFX jar with dependencies bundled - java

I just made a question about using javafxpackager to make JavaFX jars, you can see it here. My problem was that I couldn't include the classpath in the manifest. Well, while I was waiting for the answer, I tried maven-antrun-plugin instead. It worked nice, and I could run my application with dependencies, BUT (there is always a but) only with the dependencies OUTSIDE my final jar. So it is like that:
FinalJar.jar
lib
|_{all dependencies here}
My manifest file is pointing to the dependencies via the JavaFX-Class-Path property. If I put the dependencies inside the jar, like I want, it doesn't find my dependencies. Any help?
EDIT: Here's the step to add the dependencies to the jar, its inside the pom.xml:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antrun-plugin</artifactId>
<version>1.6</version>
<executions>
<execution>
<phase>package</phase>
<configuration>
<target>
<taskdef name="jfxjar" classname="com.sun.javafx.tools.ant.FXJar"
classpathref="maven.plugin.classpath" />
<jfxjar
destfile="${project.build.directory}/dist/${project.build.finalName}">
<fileset dir="${project.build.directory}/classes" />
<!-- Adds the dependencies to jar -->
<fileset dir="${project.build.directory}/lib/" includes="*.jar" />
<application name="${project.name}" mainClass="com.google.code.mzplay.principal.PrincipalFX" />
<resources>
<!-- Adds the dependencies to classpath -->
<fileset dir="${project.build.directory}/lib/" includes="*.jar" />
</resources>
</jfxjar>
</target>
</configuration>
<goals>
<goal>run</goal>
</goals>
</execution>
</executions>
<dependencies>
<dependency>
<groupId>com.oracle</groupId>

<version>${javafx.version}</version>
<systemPath>${java.home}/lib/jfxrt.jar</systemPath>

</dependency>
</dependencies>
</plugin>


In the end, my "build" part of the POM became this (you can see that it has a weld part also), its been a long time since I used it, so I don't even know if its ok anymore

It is much easier to use maven-shade-plugin. It builds one big fat jar with all dependencies inside. You can use this in combination with javafx-maven-plugin. I also tried different approaches and played around a long time and this solution was the only one which really works. Additionally, it was easy to set up.
Here is what you have to add to your pom.xml:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>3.1.1</version>
<configuration>
</configuration>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<transformers>
<transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>your.package.name.Main</mainClass>
</transformer>
</transformers>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>com.zenjava</groupId>
<artifactId>javafx-maven-plugin</artifactId>
<version>8.8.3</version>
<configuration>
<mainClass>your.package.name.Main</mainClass>
</configuration>
</plugin>
</plugins>
</build>
Change your package name inside mainClass for shade and also javaFx plugin and you are done. Now you can build your Application as always with mvn package.


Do you want to get some native applictation ? like exe or dmg。
It's my solution.
make project as a maven project first,and then add some plugins to hit the target;
i will share my pom.xml add those two plugins in you pom.xml, and run "mvn jfx:native" in you terminal later.
<!-- this plugin will copy dependencies into target application-->

First mvn compile fails to find generated sources

I use an annotation processor that creates sources in target/generated-sources/annotations/
When these generated sources don't exist I get an error if I run mvn compile
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.10.1:compile (default-compile) on project project-name: Compilation failure
[ERROR] /path/src/main/java/org/acme/dao/SomeClass.java:[39,19] cannot find symbol
It fails, but it creates the sources, so if I run mvn compile again it works.
Is there a plugin/configuration that I can add to pom.xml so it works the first time, please?
Here's the section of my pom.xml that might be relevant:

I found a workaround for this problem here:
https://community.oracle.com/tech/developers/discussion/comment/6500306/#Comment_6500306
I basically split the compiler execution and ignore the failure of the first compilation (compilation should not happen anyway).
So the important piece here is <failOnError>false</failOnError>:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.10.1</version>
<executions>
<execution>
<id>process-annotations</id>
<phase>generate-sources</phase>
<goals>
<goal>compile</goal>
</goals>
<configuration>
<failOnError>false</failOnError>
<compilerArgs>
<arg>-proc:only</arg>
<arg>-implicit:none</arg>
<arg>-processor</arg>
<arg>com.github.tivrfoa.mapresultset.MappingProcessor</arg>
</compilerArgs>
</configuration>
</execution>
<execution>
<id>default-compile</id>
<phase>compile</phase>
<goals>
<goal>compile</goal>
</goals>
<configuration>
<compilerArgs>
<arg>-proc:none</arg>
</compilerArgs>
</configuration>
</execution>
</executions>
</plugin>
It's not exactly the solution that I wanted, but it does the job.
I had to this way because javac is not respecting -proc:only
But maybe I'm missing something. Let's hope someone has a better answer. =)

the "modern" way to plug annotation processors in ~recent (>5 years old) jdk and maven is following:
<dependencies>
...
<dependency>
<groupId>some-group</groupId>
<artifactId>some-processor</artifactId>
<version>${version}</version>
<scope>provided</scope>
</dependency>
...
</dependencies>
i.e. just add annotation processor as a dependency with scope=provided and remove outdated configurations.

Maven can't retrieve buildNumber while package the jar

I am using a buildnumber-maven-plugin to generate a sequence number for my jar. I will use it during my CICD process.
I followed all the examples available online. However, I can get the ${buildNumber} to print it, but while packaging the jar, I can't get the number, and I got the ${buildNumber} text. I searched for Maven LifeCycle, and I found I need to add it in the validation before any other plugin. But still, I can't solve the issue.

Note: If I run validate I could found the echo message below which means I can get the number correctly from the properties file. If I run package or run I got ${artifact.id}_source-.0.1.${buildNumber}.snapshot without the number.
main:
[echo] current build number is "90"
I also checked this similar question here & enter link description here and other links but can't figure out the problem.

I think what's happening here is that Maven resolves properties near the beginning of the build process.
<build.number>${buildNumber}</build.number>
<model.version>${major.minor.version}.${build.number}.${build.type}</model.version>
When it resolves build.number, ${buildNumber} does not have a value. So, it leaves the variable name unchanged. And I suspect you'd have the same problem if you modified model.version to this:
<model.version>${major.minor.version}.${buildNumber}.${build.type}</model.version>
for the same reason.
You can try using the build-helper-maven-plugin as described in this answer. However, this still may not work since model.version is used as the value of the project.version, which is resolved quite early as it's part of the GAV coordinates. It's worth a try though.

Fitnesse Maven Linux run

I am trying to run FitNesse in CentOS using this profile:

</java>
</tasks>
</configuration>
<goals>

<groupId>org.fitnesse.plugins</groupId>
<artifactId>maven-classpath-plugin</artifactId>
<version>1.6</version>
<scope>runtime</scope>
</dependency>
</dependencies>
</profile>
I am using maven.classpath to add the dependency jars into Fitnesse
${maven.classpath}
But in this case i am getting
undefined variable: maven.classpath
Note: I am able to see FitNesse wiki page.

To use the plugin you have to make sure it is available to the wiki (I usually use maven dependency plugin to copy it to the wiki's plugins directory). Just adding it as a maven dependency does not suffice.
<plugin>
<artifactId>maven-dependency-plugin</artifactId>
<version>3.0.0</version>
<executions>
<execution>
<id>copy-plugins</id>
<phase>generate-resources</phase>

<overWrite>true</overWrite>
</artifactItem>
</artifactItems>
<outputDirectory>${project.basedir}/wiki/plugins</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
Furthermore you have to (copied from the README):
Add the following line to plugins.properties:
SymbolTypes = fitnesse.wikitext.widgets.MavenClasspathSymbolType
Refer to the pom file as follows:
!pomFile /path/to/pom.xml
you can define the file as pom.xml#compile to include a specific scope.

Two things -
You should be aware what relocation does is not "...relocated the httpClient dependency" but as the source suggests -
If the uber JAR is reused as a dependency of some other project,
directly including classes from the artifact's dependencies in the
uber JAR can cause class loading conflicts due to duplicate classes on
the class path. To address this issue, one can relocate the classes
which get included in the shaded artifact in order to create a private
copy of their bytecode
When you execute the mvn dependency:tree it would display all the dependencies(direct and transitive) included in your project. Instead, the maven shade plugin
shade:shade is bound to the package phase and is used to create a
shaded jar.
renaming or optimizing the dependencies further. Here goes the details for Maven Shade Plugin -
This plugin provides the capability to package the artifact in an
uber-jar, including its dependencies and to shade - i.e. rename - the
packages of some of the dependencies.

The dependency is not removed from original POM, so the behavior of dependency:tree is correct.
Shade plugin will also generate a new POM (dependency-reduced-pom.xml) wherein shaded dependencies are removed from the <dependencies> section. This looks like the one you are after.

Scala Eclipse IDE compiler giving errors until "clean" is run

I am writing a mixed Java/Scala project and my Eclipse compiler is giving errors for all of the Scala code. It seems to try to compile it as Java instead of Scala. However, when I run a clean, all of the errors go away. Also, building this using maven works completely fine.
I am building this project in Maven. Originally this project was only Java, so I added the necessary plugins/dependencies into my pom.xml.
Any idea why Eclipse is treating my Scala files as Java?
Here's my pom.xml:
