Solved Build problems after converting to Maven.

I've done the conversion, but I think there's something wrong with my POM.xml because my Bukkit plugin won't compile (build), because it doesn't know about Material.HARD_CLAY, which makes me think that it's using the wrong Bukkit API.

Here's my POM.xml:

If anyone wants to try to build my plugin (to replicate & diagnosis the problem), it's at
https://github.com/Europia79/Demolition
Make sure you
1. rename POM.xml.txt to POM.xml
2. delete build.xml
3. delete /nbproject/ directory

I'm using Netbeans, and when I do this, and it does recognize the project as Maven... It just doesn't build. I think my pom.xml error might be in the Dependency section for the Bukkit version ? But maybe the error is in the Build section ?

I've been working on this all night (with no sleep) because I really wanna convert and build. Any help would be greatly appreciated !

Still trying to figure this out. Anyone have any ideas ?

I might have to use Ant+Ivy instead... Or maybe try Intellij instead of Netbeans.

EDIT by Moderator: merged posts, please use the edit button instead of double posting.

 

Not sure if it could be an issue, but your pom.xml is infact named pom.xml.txt

EDIT: Cloned the repository you linked and built it with Maven, and it has built fine.

 

Why are you providing a bukkit jar instead of using the bukkit repo? repo.bukkit.org

 

I'm not familiar with Netbeans, but are you sure your compiling with maven and not the compiler? It's a common mistake with Eclipse and IntelliJ.

Did you actually install Maven?

 

amhokies Yeah, I went back to Ant build script when the IDE was messed up AND stopped recognizing Material.HARD_CLAY. But I didn't want to lose all my work that I did on Maven, so I saved my pom.xml into a text file. Thanks for helping.

Yeah, it builds. Just not inside the IDE, unfortunately.

Alshain01 Maven is packaged with Netbeans. You don't have to download it, but I did in order to have it on the command line. Netbeans works differently than Eclipse. In Eclipse, you export to JAR. In Netbeans, you build a JAR with Ant or Maven.

Here's some code that I did to help someone out on the forums. It shows that Netbeans is building with the pom.xml

I'll convert back to a Maven project for Demolition and post the results.

epicfacecreeper Hopefully this is the problem. What would be the XML option to change this ?

In the IDE version, you are using the wrong bukkit version. Change the <version> tag in the bukkit dependency.

I used Bukkit.jar #1903 when I started:

HTML:

<version>1.7.2-R0.3</version>

https://forums.bukkit.org/threads/nullpointer-exception.252509/#post-2383056
I was helping out the above person and started a Maven project to test it when he said "it didn't work."
So actually, just now, I got the idea to see if Material.HARD_CLAY works in that project... And it does work.
I was about to post the POM.xml so that we could check out the differences: But I took a quick look, and it had the "maven-compiler-plugin"
So I inserted this into my Demolition project's pom.xml and the project now builds in the IDE:

HTML:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.1</version>
  <configuration>
      <source>1.6</source>
      <target>1.6</target>
  </configuration>
</plugin>

Thanks for helping everyone! Hopefully this will help other Netbeans users... And users new to Maven.
