Maven gephi_plot issue "org.gephi:gephi-toolkit:jar:0.8.2" missing

[lukdo]

Hello,

I want to plot my graph with the json files using the gephi_plot file.
As explained I use "mvn compile assembly:single" command.

I get his error:

---

[INFO]
[ERROR] BUILD ERROR
[INFO]
[INFO] Failed to resolve artifact.

Missing

1. org.gephi:gephi-toolkit:jar:0.8.2

Try downloading the file manually from the project website.

Then, install it using the command:
mvn install:install-file -DgroupId=org.gephi -DartifactId=gephi-toolkit -Dversion=0.8.2 -Dpackaging=jar -Dfile=/path/to/file

Alternatively, if you host your own repository you can deploy the file there:
mvn deploy:deploy-file -DgroupId=org.gephi -DartifactId=gephi-toolkit -Dversion=0.8.2 -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]

Path to dependency:
1) com.lab41.circulo:gephi_plot:jar:0.0.1-SNAPSHOT
2) org.gephi:gephi-toolkit:jar:0.8.2

I can't find the org.gephi:gephi-toolkit:jar:0.8.2 document online

---

So I changed in the gephi pom.xml just to test:

        <artifactId>gephi-toolkit</artifactId>
        <version>0.8.2</version>

to

                    <artifactId>gephi-toolkit</artifactId>
                    <version>0.9.1</version>

but it lead to a lot of warnings and:

[ERROR] COMPILATION ERROR :
[INFO] -------------------------------------------------------------
[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?
[INFO] 1 error
[INFO] -------------------------------------------------------------
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD FAILURE

I don't know what to do. Any clue would be a great help.

Thank you for reading
