LifeRay: When I build the war, my changes are removed

问题

I have setted up a liferay environament with eclipse and tomcat (first time I use any of them),

And I want to make some changes, for example, I add a <p> in the end of the navigation.vm:

But when I build the war, like this:

My change dissapears:

Any idea what I'm doing wrong?

回答1:

probably you're trying to edit the portal-normal.vm under

yourTheme/docroot/templates

but you can't. You have to create a new folder called _diffs under

yourTheme/docroot

in which you copy the folders structure of docroot, in this case you need only of template folder in which create a new file called portal-normal.vm.

And that will be the file you can edit!

for more details : https://www.liferay.com/it/documentation/liferay-portal/6.1/development/-/ai/creating-liferay-them-7

PS
Obviously you can copy the original content of portal-normal.vm

PPS
I really don't know why liferay does not create the _diffs folder as default of a theme project!

EDIT

I forgot to say that you have to copy the folder structure of docroot in _diffs

回答2:

In other words... if you don't want to see the content removed of the files *.vm (for example portal_normal.vm) you must first create a folder templates in the folder docroot/_diffs with the files *.vm.

When we generate the WAR file, will automatically take the changes and you will see them in the folder docroot/templates/*.vm and also in the WAR file.
