Dev Troubleshooting
This page shall list small issues / tips when developing for sw360.
Before building the sw360portal with maven, ensure that the following components are installed in the development environment:
- A git client
- Apache Maven 3.0.X
- Apache Thrift 0.9.3
- Java 1.8.X
- CouchDB, at least 1.5 (only if the tests will be executed locally)
Please do not use Eclipse, because the integration of Apache Thrift is an open issue and we found no plugin for Eclipse to solve the shown compiler errors. Recommended is IntelliJ IDEA or NetBeans.
When developing changes to a page and these changes do not show in browser - even after redeployment, then the internal liferay optimisation mechanisms may kick in. Try to add to the URL string the following key value parameters:
js_fast_load=0&css_fast_load=0&strip=0
It is the file portal-ext.properties in sw360/opt.
You just try to compile parts or all of it and it fails? Most of the stuff depends on the module /build-configuration. Execute either "mvn install" on top level or inside build configuration.
maybe try instead:
/opt/apache-tomcat-/bin/startup.sh
just this:
CATALINA_OPTS="-Dhttps.proxy..." /opt/apache-tomcat-/bin/startup.sh
for lucene it might be necessary to add:
[httpd_global_handlers]
_fti = {couch_httpd_proxy, handle_proxy_req, <<"http://127.0.0.1:8085/couchdblucene">>}
in lucene.ini of local.d of your CouchDB installation
- Check tomcat manager (if the services are there)
- Check if the service is accessible:
Should return "Welcome to ...".
http://your.url.to.server.com:8085/components - Check if the service thrift page is there:
Should return HTTP status code 500, because in the browser, no valid thrift message was formed.
http://your.url.to.server.com:8085/components/thrift
What do I do if I get: org.ektorp.DbAccessException: com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException: Unrecognized field "_id"
You add the class you have been trying to serialize to THRIFT_CLASSES in sw360/src/libraries/lib-datahandler/src/main/java/com/siemens/sw360/datahandler/thrift/ThriftUtils.java
If the deployment via maven of the backend does fail with an error like this

One solution is that you deployed already and the tomcat7 plugin does not like to have multiple deploy commands. Instead you will need to issue a mvn tomcat7:redeploy command.
If the virtual machine was shut down and started up again, the backend services and frontend liferay require manual restart. Please contribute a change in the vagrant deployment if you feel that this could be changed. The actual places to call are:
/opt/apache-tomcat-.../bin/.startup.sh
/opt/liferay-.../tomcat-.../bin/.startup.sh
