Development Environment Setup Walkthrough

Development Environment Setup Walkthrough

Jan 16, 2019

Information

This is a walkthrough for setting up a Sakai development environment on a laptop or desktop. These instructions will also work for setting up a development server though I suggest slightly beefier settings for memory. This is currently tailored for Sakai 2.9+. Once you have a Sakai development environment setup you should be able to program your own Sakai tools or modify existing tools.

Notes for developers using older versions of Sakai (2.8.x-)

Notes for windows users

  • change the "/" to "\" for all directory paths except those specified in the maven build.properties file

  • add the drive letter (C:) to your paths

  • use %VARIABLE% instead of $VARIABLE with environment variables

  • set your environment variables in Control Panel -> System -> Advanced -> Environment Variables

All of sakai and related programs should be installed in an opt directory which you will need full write access to, put this directory anywhere you want, this document will assume you have placed it in your root directory

  1. Install/Verify you have Java 1.7

  2. Install/Verify you have MySQL 5.1 or later 

  3. Setup Sakai DB (schema) and user

    1. Create the sakai database and sakai user (password=ironchef)

    2. Run the following from a command line prompt:

      mysql -u root -p

      • Note: You can also do the following if you prefer to be prompted for the password: mysql -uroot -p

    3. Then run these commands from the mysql prompt (one command per line):

      create database sakai default character set utf8; grant all privileges on sakai.* to 'sakai'@'localhost' identified by 'ironchef'; grant all privileges on sakai.* to 'sakai'@'127.0.0.1' identified by 'ironchef'; flush privileges; quit

    4. [Optional] Download and install mysql query browser

      1. http://dev.mysql.com/downloads/query-browser/1.1.html

      2. You do not have to do anything with query browser now

  4. Download and setup Maven 2.2.x+ stable package

  5. Install/Verify you have Subversion

  6. Download and setup tomcat 7.0.21+ (stable only)

  7. Download and setup MySQL Connector/J stable

  8. Use Subversion to download sakai code (Sakai 10 and earlier) or use Git/Github to download sakai code (Sakai 11 and later)

    1. Change to the /opt directory

    2. Checkout source from trunk (absolute latest stuff) or a release branch or tag:

      1. Trunk: svn checkout https://source.sakaiproject.org/svn/sakai/trunk/ sakai-trunk

      2. 2.9.x Branch: svn checkout https://source.sakaiproject.org/svn/sakai/branches/sakai-2.9.x/

      3. If you want a version other than these, browse the tags and branches at https://source.sakaiproject.org/svn/sakai/

    3. Checkout will take about 5-10 minutes

    4. The directory created by subversion will be referred to as <sakai-src> directory (this could be whatever you want; above examples use 'sakai-trunk' and 'sakai-2.9.x')

  9. Setup sakai.properties file

    1. Create sakaidirectory in $CATALINA_HOME

      • $CATALINA_HOME should be /opt/tomcat if you have been following these instructions

    2. Copy the default config from default.sakai.properties to $CATALINA_HOME/sakai/sakai.properties

    3. Edit the sakai.properties file for a MySQL dev environment. Starting at the section marked # DATABASE:

      1. Set BaseDataSource username

        1. Set username@javax.sql.BaseDataSource=sakai

      2. Set BaseDataSource password

        1. Set password@javax.sql.BaseDataSource=ironchef

      3. Find the section: # HSQLDB settings and verify following lines are commented out

        # HSQLDB settings (DEFAULT) #vendor@org.sakaiproject.db.api.SqlService=hsqldb #driverClassName@javax.sql.BaseDataSource=org.hsqldb.jdbcDriver #hibernate.dialect=org.hibernate.dialect.HSQLDialect #validationQuery@javax.sql.BaseDataSource=select 1 from INFORMATION_SCHEMA.SYSTEM_USERS # Two hsqldb storage options: first for in-memory (no persistence between runs), second for disk based. #url@javax.sql.BaseDataSource=jdbc:hsqldb:mem:sakai #url@javax.sql.BaseDataSource=jdbc:hsqldb:file:${sakai.home}db/sakai.db

      4. Find the section: # MySQL settings and uncomment the 6+ lines in it

        # MySQL settings vendor@org.sakaiproject.db.api.SqlService=mysql driverClassName@javax.sql.BaseDataSource=com.mysql.jdbc.Driver hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect url@javax.sql.BaseDataSource=jdbc:mysql://127.0.0.1:3306/sakai?useUnicode=true&characterEncoding=UTF-8 validationQuery@javax.sql.BaseDataSource=select 1 from DUAL defaultTransactionIsolationString@javax.sql.BaseDataSource=TRANSACTION_READ_COMMITTED

    4. Save the changes to the sakai.properties file

       

  10. Create maven settings.xml file

  11. Use Maven to build Sakai

    1. Open a command line shell

    2. Change directory to /opt/<sakai-src>

    3. Execute mvn clean install to build Sakai using maven

      • Note: The build will take an extra 5-10 minutes to download dependencies the first time

    4. Execute mvn sakai:deploy to deploy Sakai to your tomcat using maven

    5. Partial builds are supported by the maven2 build system
      You can now do a "mvn clean install sakai:deploy" from any subdirectory and build just that code

    6. Once you have downloded the jars you can run maven off-line with mvn -o clean install sakai:deploy

  12. Start Tomcat and check to make sure Sakai runs

    1. Start tomcat using $CATALINA_HOME/bin/startup

    2. Allow 1 minute+ for tomcat to start up

    3. Open http://localhost:8080/ to verify tomcat is running

    4. Open http://localhost:8080/portal to verify sakai is running

    5. Login to sakai as username:admin, password:admin

    6. Shutdown Tomcat using $CATALINA_HOME/bin/shutdown

  13. Install Eclipse 3.2+ stable

  14. Add subclipse to Eclipse

  15. Add Maven Eclipse Plugin to Eclipse

  16. Add Lombok plugin to Eclipse [OPTIONAL]

    1. Shutdown eclipse

    2. Follow the steps on the page linked above

    3. Restart eclipse

    • NOTE: this is only required for certain parts of the code that use the lombok library (a limited set)

  17. Import Sakai source code into Eclipse
