Problem building project about pdi-sdk-plugins

[dstandish]

I was getting a similar error. I copied this settings.xml file to ~/.m2 and it worked.

I've installed manually the plugin in my report now running the commad I'd this error

Can you help me?

Pentaho 7.0 and later only compile with Java 8. You may need to investigate which JDK version you are using to compile the project.

When I run mvn clean package site I get this error:

[ERROR] Plugin org.jacoco:jacoco-maven-plugin:0.7.7-SNAPSHOT or one of its dependencies could not be resolved: Could not find artifact org.jacoco:jacoco-maven-plugin:jar:0.7.7-SNAPSHOT -> [Help 1]

What is the workaround?

[jknight]

@asheesharora I'd gotten this error as well but it's working now - please update & retest to see if it works for you now

[myobis]

I'm facing the exact same issue as @asheesharora with a fresh download from this morning (latest commit 5 days ago).
[Help1] refers to http://cwiki.apache.org/confluence/display/MAVEN/PluginResolutionException

I'm quite new to maven.. Is it possible that JaCoCo v0.7.7 cannot be found where expected (where would it be ?).. If yes, maybe we could download it manually (well, not sure where I'd put exactly.. maybe somewhere under .m2\repository ).

[jknight]

I just did a fresh git clone https://github.com/pentaho/pdi-sdk-plugins.git / mvn clean package site and got "BUILD SUCCESS".

I have:

• .m2/repository/org/jacoco/jacoco-maven-plugin/0.7.7.201606060606/jacoco-maven-plugin-0.7.7.201606060606.jar

And:

• Apache Maven 3.3.9
• java version "1.8.0_25"

Hi,
Thanks for this information @jknight . Indeed, this one succeeds.
The point is (and sorry for not mentioning it before), I was trying to build for the 7.0 branch as I need to build step plugins for the latest stable version mentioned on the community site and available on SourceForge (7.0.0.0-25).

Unfortunately, even now that JaCoCo is in .m2/repository (same as you mentioned), the 7.0 branch still fails to compile.
I tried to compare master and 7.0 with no success.. Not sure what to look after.. any clue would be appreciated.

I'm using Maven 3.3.9 and JDK 1.8.0_121 .

@myobis - I tested building the current pdi-sdk-plugins by installing the demo step plugin into PDI v7.0 and it worked for me. My guess is that the latest of pdi-sdk-plugins is compatible with PDI v7. Here's what I did.

From a shell / command prompt:

• Get latest
  • git clone https://github.com/pentaho/pdi-sdk-plugins.git
• Build parent
  • mvn clean package site (BUILD SUCCESS)
• Build demo step plugin:
  • cd kettle-sdk-step-plugin
  • mvn package (Building zip: [...]/target/kettle-sdk-step-plugin-7.1-SNAPSHOT.zip)
• "Deploy" plugin by moving/copying it to the pdi plugins directory (v7.0.0.0-25)
  • mv [...]/target/kettle-sdk-step-plugin-7.1-SNAPSHOT.zip [...]/pdi-ce-7.0.0.0-25/plugins
• Start spoon
  • bash [...]/pdi-ce-7.0.0.0-25/spoon.sh
• Under design, search for "Demo": it appears under 'transform'

[myobis]

Thank you so much. 👌
Indeed, I noticed that it works but I was a bit afraid to consider using plugins built on a version not synchronized to PDI itself.
To confess, even my old plugins compiled for PDI v4.2.0 are -at least apparently- working with v7.0.
So I was a bit uncomfortable to propose that for production use.

Now, let's get pragmatic : It it passes our internal tests, (and PDI is pretty convenient to create test transformations)... that's probably fine enough as the version gap is more reasonable.
