Eclipse, Maven, pom.xml error

[Ezio Ostorero]

  Good Morning All,

  Disclaimer, I'm a Camunda newbie, therefore I'm starting from here: http://docs.camunda.org/7.2/guides/getting-started-guides/developing-process-applications/#set-up/eclipse

  Couldn't reach first base, tough :-|

  The supplied pom.xml file looks like broken, or there's something missing in my installation.
  I got this set of errors:

Multiple annotations found at this line:
    - Plugin execution not covered by lifecycle configuration:
org.apache.maven.plugins:maven-resources-plugin:2.5:testResources
(execution: default-
     testResources, phase: process-test-resources)
    - Plugin execution not covered by lifecycle configuration:
org.apache.maven.plugins:maven-resources-plugin:2.5:resources (execution:
default-resources,
     phase: process-resources)
    - Plugin execution not covered by lifecycle configuration:
org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (execution:

     phase: compile)
    - Plugin execution not covered by lifecycle configuration:
org.apache.maven.plugins:maven-compiler-plugin:2.3.2:testCompile
(execution: default-
     testCompile, phase: test-compile)

  I did my share of googling and research, looks like the problem is well known, and widespread, in both Camunda and more generally M2E environments.

  I foud a good share of "try this", "maybe that", "add a plugin section", but no clear and reliable solution.

  Any ideas?

  Thanks in advance for your support,

Hi Ezio,

which line of the pom.xml seems to be broken for you?

Cheers,

Sebastian

  Hello Sebastian!!

  The highlighted section looks to be this one:

  <packaging>war</packaging>

  For sake of completeness, here's my environment:

  OS: Mac OS X 10.8.5

  Eclipse: Kepler 20140224-0627

  Ciao,

Hi Ezio,

sorry but the pom is valid and this seems to be a problem with your eclipse installation. I'm not using eclipse by myself so I can't help you with this. Sorry.

Cheers,

Sebastian

Hi Ezio,

Does the issue prevent you from building the project in eclipse? I personally tend to ignore these issues unless they prevent building.

Cheers,

Hi Thorben.

  Well I was hoping that Maven could take the hasse of building a Java project off from me :-|

  So, I will have to do it the good? old way.
  Or, I can run the Maven build from command line.

  Neither is exactly straightforward ... I'll give it a try. Not being a Maven expert will bring me some hard time.

  Too bad, I am interested in BPM, but I'm pretty much stuck in Java, Maven and Eclipse nuts and bolts.

  Ciao,

Hi Ezio,

That is not exactly what I mean. Please do use Maven ;). It's just the eclipse integration that behaves strangely sometimes.

What happens if you attempt to build the project with Maven in eclipse? I.e. Right click on the project -> Run as -> Maven build with goals "clean install".

If you have maven installed as a command line tool, you can also build from command line. Some people prefer that anyway. You'll have to install Maven as a standalone application then (meaning that having only the m2eclipse plugin installed is not sufficient), see [1].

Cheers,
Thorben

  Hi again Thorben.

>It's just the eclipse integration that behaves strangely sometimes

  Yup. From what I've been reading recently, that integration is erratical, at best.

>If you have maven installed as a command line tool, you can also build from command line. Some people prefer that anyway.

  YEAH! I'm an old-time Unix guy ... well nothing beats the command line :-)

  I have mvn installed as an utility on my Mac, so running it seems so far to be somehow working.

ezio$ mvn --version
Apache Maven 3.0.3 (r1075438; 2011-02-28 18:31:09+0100)
Maven home: /usr/share/maven
Java version: 1.8.0_45, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_45.jdk/Contents/Home/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "mac os x", version: "10.8.5", arch: "x86_64", family: "mac"

  As for M2N:

>Right click on the project -> Run as -> Maven build with goals "clean install".

  I think here's the problem. "Run as" has no knowledge of Maven.
  "Run as" leads to "Run Configurations..." that brings up a pop-up with many choices, none of them looks like Maven.

  So I believe my Eclipse is confused: it is OK to create a Maven project, but not OK to run it.

  Thank you for your attention,

Well!!

It looks like the cmd-line mvn plus deploy is working fine.

Thank you Thorben for your advice.

  Ciao,
