Java 1.8 to 12

[Alexey]

I have an external jar file that only works successfully on Java 12. In Cytoscape, I work with JDK 13, but  <Target bytecode version> =1.8 in Java Compiler settings .

Now in pom.xml:

 

<version>3.0</version>

...

<source>1.8</source>
<target>1.8</target> 

I replaced with:

 

<version>3.8.1</version>

...

<release>12</release>

This causes a error.

I don't know much about maven and I want to understand what I'm doing wrong. Thank you!

Probably I formulated the question too incorrectly. I'll try a simpler task. I created a simple jar file that contains only two classes and included it in dependencies:
<dependency>
<groupId>dp.stud.code</groupId>
<artifactId>deptest</artifactId>
<version>1.0</version>
</dependency>

I can use classes from this jar-dependency for example in the CyActivator class. I am building the plugin and I am not getting any errors, however such a plugin does not work in cytoscape. 
Then I added this line to pom.xml : <Embed-Dependency>groupId=dp.stud.code</Embed-Dependency>. But nothing works.

Hi Alexi,

    First, I think you would be better off targeting Java 11, which is required by Cytoscape 3.8.  Second, as far as what you need in maven to include the dependency, take a look at the clusterMaker2 pom.xml file, which includes a number of external dependencies.  You can find it here: https://github.com/RBVI/clusterMaker2/blob/master/pom.xml.  Look for some of the jung includes as an example.  Note that I had to install those packages in my local maven archive by doing mvn install.

Actually, I would also note David's response to Lauren.

Thanks! I add my test jar-file to the project and everything works. But now when I install the third party jar file in the same way the plugin doesn't work.

If I understand correctly, it says here that net.sf.tweety.logics.pl.syntax is missing, but this package is already inside net.sf.tweety.tweety-full. 

in pom.xml :

<Embed-Dependency>tweety-full</Embed-Dependency>

<Embed-Transitive>true</Embed-Transitive>

<dependency>
<groupId>net.sf.tweety</groupId>
<artifactId>tweety-full</artifactId>
<version>1.17</version>
</dependency>

Hi Alexey,

   Looks like it isn't getting properly embedded.  Here is a snippet of my pom.xml where I do embed lots of dependencies:

         <instructions>
            <Bundle-SymbolicName>${bundle.symbolicName}</Bundle-SymbolicName>
            <Bundle-Version>${project.version}</Bundle-Version>
            <Export-Package>!${bundle.namespace}.*</Export-Package>
            <Private-Package>${bundle.namespace}.*,com.jujutsu.*</Private-Package>
            <Bundle-Activator>${bundle.namespace}.CyActivator</Bundle-Activator>
            <Embed-Dependency>*;scope=!provided</Embed-Dependency>
            <Embed-Transitive>true</Embed-Transitive>
            <Import-Package>*;resolution:=optional</Import-Package>
          </instructions>

and then in the dependency itself:

    <dependency>
      <groupId>org.ojalgo</groupId>
      <artifactId>ojalgo</artifactId>
      <version>45.1.0</version>
      <optional>true</optional>
    </dependency>

note the "<optional>true</optional>".  That seems to work for me (although I honestly don't know why this particular piece of arcana is necessary).
