Tutorial-Maven Archetypes

Maven Archetypes

• Building Archetypes
• Using Archetypes

To ease in development of e-Science Central blocks and libraries using your desktop computer a set of maven archetypes is provided. These archetype generate a ready-to-use block or library templates which you can build, upload and test in your instance. They are a good starting point to code your blocks.

However, before you can use any of the archetypes you need to build them.

Building Archetypes

The archetypes are placed in the code repository under the /code/tools/maven directory.
To compile, build and install archetypes in your maven repository run commands:

cd /code/tools/maven
mvn install

Using Archetypes

You can use the maven archetypes to generate blocks for Java, JavaScript, Octave, R. Under /code/tools/maven you will find all available artifacts named workflow-block-*.
There's also an archetype to generate an e-Science Central binary library workflow-library.

For example, to generate a Java block template using maven issue (on Linux):

mvn archetype:generate \
    -DarchetypeGroupId=com.connexience \
    -DarchetypeArtifactId=workflow-block-java \
    -DarchetypeVersion=3.1-SNAPSHOT \
    -DgroupId=org.myblocks \
    -DartifactId=FirstOne \
    -Dversion=1.0 \
    -DinteractiveMode=false

and on Windows (change '\' to '^'):

mvn archetype:generate ^
    -DarchetypeGroupId=com.connexience ^
    -DarchetypeArtifactId=workflow-block-java ^
    -DarchetypeVersion=3.1-SNAPSHOT ^
    -DgroupId=org.myblocks ^
    -DartifactId=FirstOne ^
    -Dversion=1.0 ^
    -DinteractiveMode=false

Note: if this command fails reporting: The desired archetype does not exist (com.connexience:workflow-block-java:3.1-SNAPSHOT), you need to build the archetypes first; please refer to the section above.
