I had the same issue while trying to compile the SDK, you can try this url: https://repository.liferay.com/nexus/content/repositories/liferay-public-snapshots/com/liferay/org.apache.ivy/2.4.0.LIFERAY-PATCHED-1-SNAPSHOT/. Instead of the old one.
They apparently change the repository of Liferay, you can check it on Date Modification on :https://repository.liferay.com/nexus/content/repositories/.
Steps/Prerequisite for liferay on windows:
Firstly we need liferay IDE, which we can download from https://web.liferay.com/downloads/liferay-projects/liferay-ide , If you dont have eclipse editor select eclipse neon 2+liferay IDE. Or if you are having eclipse go for update archive file.
Second we need liferay plugin sdk here’s the link: https://www.liferay.com/downloads , under liferay portal CE(Community Edition) select plugins sdk.
Third, you need to download apache ant.
Download tomcat bundle from link provided in 2nd point.
Setup ANT_HOME, ANT_OPTS, CATLINA_HOME,JAVA_HOME,and JRE_HOME, and append their path accordingly in the Path field.
Let’s configure the sdk file before moving next. Keep the bundled tomcat and sdk extracted files at same folder location(mandatory). That is keep same extraction folder for tomcat and sdk plugins.
In plugins folder which you would extract, you’ll find build.properties. Replicate that file with build.username.properties. For example in my case it would be build.Jennis.properties, Keep in mind the case of the Username of your PC/laptop. And add the following line of code at the end of the file
app.server.dir=path_to_sdk../bundles/path_to_tomcat in
build.username.porperties. In my case the appended line would be
app.server.dir=C:\Users\Jennis\Documents\Downloads\com.liferay.portal.plugins.sdk-7.0/../bundles/tomcat-8.0.32
Create a bundles folder and keep the extracted folder other than SDK plugins in bundles folder.
Now we are ready to go with directly eclipse for liferay 7.0.2 installation in eclipse. Open Eclipse →Help →Install New Software. Locate the liferay IDE archive from browse button.
Now we need to add the server for liferay, to do so right click in servers window in eclipse and click on new select liferay →liferay7.x configure it and give path to tomcat8.0.32 bundle.
Run the server it will lead you to localhost:8080, configure it with defaults(not mandatory) for our example defaults are fine.
After eclipse installs the new software, it would restart in toolbar menu find the below icon and click new liferay plugin project!
If toolbar doesn't show than find it from Window →Appearance → Show Toolbar. Now click above icon and click new liferay plugin project!
Give your portlet a name.
Select build type as: Ant(liferay-plugins-sdk).
Select liferay MVC for sake of simplicity.
Next you will be prompted with SDK location give the location of SDK plugin extracted folder, which were kept at same folder at time of extracting it.
Project would be created and celebrate the first portlet.
I have also ran into this problem. The solution was in my case to change the ivy settings in build.properties (in plugins SDK root directory) like this:
ivy.version=2.4.0
ivy.jar.url=http://repo1.maven.org/maven2/org/apache/ivy/ivy/${ivy.version}/ivy-${ivy.version}.jar
I'm however not familiar with changes Liferay made in the PATCHET version of ivy, so it could possibly lead to some other problem. But it works for portlets apparently.
Following is my addition to portal-ext.properties for setting up ImageMagick with Liferay
I have installed ImageMagick in D drive as mention below :
imagemagick.global.search.path=D:\\ImageMagick-6.8.3-Q16
imagemagick.enabled=true
preview functionality:
dl.file.entry.preview.enabled=true
dl.file.entry.thumbnail.enabled=true
Set this to true to enable conversion and previewing of videos in the Document Library portlet:
xuggler.enabled=true
In Server Administration--->External servics tab, I have configured it correctly and also downloaded/install jar related to Xuggler.
However, above settings are not working for me to generate preview functionality.
I am not even getting message dispalyed like "Generating preview require few more time, please refresh the page after some time....blah blah blah...."
Any help is appreciated.
Thanks.
Have you configured Xuggler properly? Do you get an UnsatisfiedLinkError exception?
See Xuggler's FAQ for the steps to configure your path properly
If it shows that message "Generating preview...", seems that Liferay doesn't detect this file as a video file (the Mime Type isn't any of the values in the property: dl.file.entry.preview.video.mime.types).
I also saw this problem when uploading videos using some browsers. Try uploading using another one.
For me, the solution was to symlink /usr/bin/convert to /usr/local/bin/convert
Whatever I did, nothing seemed to work. All configuration was pointing to /usr/bin (both control panel and portal-ext.properties). As a last resort, not really believing that it will work, I just did the symlink, as that was the default location for liferay.
And it works! All my configuration still points to /usr/bin. So... it looks like liferay just ignores all that config and only looks to default folder.
I'm using Ubuntu 12.04, imagemagick from package manager. Liferay 6.1.2 GA3.
I hope it helps someone.
I have created a sample Liferay portlet and it has successfully deployed. But, the eclipse console didn't say "1 portlet is ready for use". And, I couldn't find this portlet in the Add >> More.. option on a Liferay page.
As Mark mentioned, it is undeterministic and it sometimes happen. I usually follow the following steps and after this it works normally.
Steps:
remove all the references of the portlet from webapps.
stop the server
deploy the portlet's WAR
restart the server
check the logs if the portlet is deployed.
If possible try to build the WAR again and deploy the new WAR, and follow the previous steps.
Also if this doesn't work try to clear the temp and work directory and again try the previous steps.
Hope this helps.
I have been fighting with this problem for a day. For me it was two things: wrong property of
liferay.home
inside
portal-setup-wizard.properties
Only after correction I was able too see in tomcat logs that my liferay-plugins had higher version than liferay itself. I redownload plugins with correct version and new plugin deployed correctly.
If you've done all the cleaning etc. and it still does not work, there may be another reason for not showing. If you have - for some reson - deactivated the portlet in Liferay, it will remember the setting even though you have undeployed it several times.
So, you must go to Control Panel > App Manager > All Apps > Your portlet name and activate it again!
That is undeterministc but usual error. Try to undeploy the portlet - delete portlet directory under tomcat/webapps and try to deploy again.
Liferay migration from one server to another help required. Can anyone share there steps for migration of Liferay portal 5.2.3 from one server to another. I am using Windows + Tomcat + MySql.
I have uploaded whole tomcat folder to the new windows machine and imported the database too with the corresponding change to the configuration file like Database details.
But after starting the tomcat server it is showing some error like "Unable to load repository http://plugins.liferay.com". Any idea why I am getting this error ?
These are the steps that I have followed and able to migrate the Liferay successfully:
Take the backup of Liferay files and database from first windows machine.
Install the same version of Liferay (Say Liferay 5.2.3) on second windows machine.
Shut down Liferay.
Import the database on new system.
Add portal-ext.properties with relevant entries. (e.g Datbase Name, User Name , Pasword etc)
Add \liferay-portal-5.2.3\data\document_library files from old machine.
Start the tomcat. It will automtically do the rest.
NOTE: In the above method I have not deployed Theme and custom plugins etc, you have to deploy Theme and custom plugins also that are used on old system.
Lifery is trying to connect to plugin repository to find whether there are updates for plugins.
Does your new machine have internet conectivity?
Also you have options to ignore that message or configure liferay not to check for updates.
For later put in portal-ext.properties
plugin.repositories.trusted=
plugin.repositories.untrusted=
UPDATE:
If behind proxy create (if not existent) system-ext.properties (beside portal-ext.properties) and add
com.liferay.util.Http.proxy.host=proxy_host
com.liferay.util.Http.proxy.port=proxy_port
Change proxy_host and proxy_port with your values.
Also remove from portal-ext.properties if you want liferay to check repositories
plugin.repositories.trusted=
plugin.repositories.untrusted=
Im new with liferay have a problem with portlet deployment using the plugins sdk,
Platform:
liferay-portal-tomcat-5.5-5.1.2,
liferay-plugins-sdk-5.2.2,
windows vista.
Problem:
I have successfully created a sample portlet with ant and deployed it into the hot-deploy folder. It is automatically picked up by the server but the console messages say that the portlet has been copied successfully and never registers it.. and i cant find it in the add application drop-down menu.. pls your help will be very appreciated.
I don't know if anything important changed in these versions, but you say you're using Liferay 5.1.2 with the plugin environment 5.2.2 - try with matching versions - at least on the second digit.
also, make sure that all required files are available - among them are WEB-INF/web.xml, WEB-INF/portlet.xml.
Create a new sample portlet with "create.bat" in the plugin SDK's portlet folder and deploy this - it should succeed. Then make sure that all config files from the new one are present in your current one.
How did you create your current portlet? What did you do/change?
