Create savapage-make/.project file …

savapage-make/.project

<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
    <name>savapage-make</name>
    <comment/>
    <projects/>
    <buildSpec/>
    <natures/>
</projectDescription>

… and import this project via “Import → General → Existing Projects” into Workspace.

Download/install thirdparty files in addition to SavaPage.

cd ~/savapage
wget https://www.savapage.org/download/development/thirdparty-savapage-fonts.tar.gz -O - | tar -xz

Add each Maven project with: File → Import → Maven → Existing Maven Projects.

For each project, select the project in the Project Explorer and select the project properties.

• → Checkstyle : enable “Checkstyle active for this project”.
  • “Simple - use the following check configuration for all files: Sun Checks -(Global)
• → SpotBugs : enable “Run automatically”.

Select the savapage-core project, right-click and select from main menu: Run As → Run Configurations… and Right-click on “Java Application”.

Select “New Configuration” and enter the following on tab “Main”:

On tab “Arguments” enter the following “Program Arguments”:

• ${string_prompt}
  

On tab “Arguments” enter the following “VM arguments”:

-Dserver.home=${project_loc}/../savapage-server/server.home    
-Dlog4j.configuration=file://${project_loc}/../savapage-server/server.home/lib/log4j.properties

Select “New Configuration” and enter the following on tab “Main”:

On tab “Arguments” enter the following “Program Arguments”:

• ${string_prompt}
  

On tab “Arguments” enter the following “VM arguments”:

-Dserver.home=${project_loc}/../savapage-server/server.home    
-Dlog4j.configuration=file://${project_loc}/../savapage-server/server.home/lib/log4j.properties

Embed fonts:

cd ~/savapage/repos/savapage-core
cd src/main/java/org/savapage/core/fonts/
mkdir truetype
# copy font directories from thirdparty
cp -r ~/savapage/thirdparty-savapage/fonts/savapage/0.9.7/* truetype/

• Open the savapage-core project properties
• Select the “Java Build Path → Source” → savapage-core/src/main/java source folder.
  • Make sure Included: (All) and Excluded: (None) is selected. In this way XML and PNG and .properties files used in the Jasper Reports will be present in the Output folder, as needed for testing in the Eclipse environment.
• Select the “Java Build Path → Source” → savapage-core/src/main/resources source folder.
  • Make sure Included: (All) and Excluded: (None) is selected. In this way the Hibernate META-INF/persistence.xml files will be present in the Output folder, as needed for testing in the Eclipse environment.

• Copy savapage-make/eclipse/server.home.template to savapage-server/server.home.
• Follow the instructions in the savapage-make/eclipse/server.home.template.md file.

Select the savapage-server project, right-click and select from main menu: Run As → Run Configurations…

Right-click on “Java Application”, select “New Configuration” and enter the following on tab “Main”:

On tab “Arguments” enter the following “VM arguments”:

-Dserver.home=${project_loc}/server.home 
-Dclient.home=${project_loc}/client.home 
-Dwicket.configuration=development
-Dlog4j.configuration=file://${project_loc}/server.home/lib/log4j.properties
-Dcom.sun.management.config.file=${project_loc}/server.home/jmxremote.properties
-Djava.net.preferIPv4Stack=true
-Djava.io.tmpdir=${project_loc}/server.home/tmp

• Open the “savapage-server” project properties
• Select the “Java Build Path”

IMPORTANT

• To test the savapage-ext-* projects, their target/classes folders must be added (“Add Class Folder…”) to the “Java Build Path → Libraries” of the `savapage-server` project.
• To test the savapage-i18n-* projects, their target/classes folders must be added (“Add Class Folder…”) to the “Java Build Path → Libraries” of the savapage-server project.

IMPORTANT :

• Select the “Java Build Path → Source” → savapage-server/src/main/java source folder.
• Make sure Included: (All) and Excluded: (None) is selected. In this way the Wicket *.html files will be present in the Output folder, as needed for testing in the Eclipse environment.
  • As an alternative you can also add **/*.html to the Included section (where **/*.java most probably is already present)
  • Beware: this setting might be (when?) overwritten when performing a “Maven → Update project” action.

Create directory savapage-server/client.home/ and copy SAVAPAGE.ppd to it.
