Re: Eclipse IDE and TML code completion

[Alessio Gambi]

Hi,

I managed (with some pain really) to install the tag library inside  
eclipse,

I followed the tutorial on the "Tapestry5 How Tos" and it works fine  
for installing the t5.tld entry.

But if I repeat the same procedure to install also the tld generated  
by your plugin, then eclipse either stops showing the auto completions  
or show only the last added (the ones belonging to my components).

Then - but this is eclipse - if I remove all the user defined  
catalogs, refresh, clean and update dependencies for the project,   
eclipse still shows the old auto completion tags.

The only way I managed to show all the tags (basic t5 and my  
components) is to manually merge everything inside one single tls file  
and then load just that one using
the http://tapestry.apache.org/schema/tapestry_5_1_0.xsd as Key value  
for the XML Catalog Wizard of eclipse.


I think that a nice improvement to you plugin is to either merge all  
the tlds together (basic plus all the related components library  
projects and dependencies),
or to programmatically add the tags definition to eclipse (for example  
by using some kind of eclipse plugin).

Happy to see that you could generate your TLD.

The generated XML "tldgen-components-info.xml" is a temporary file  
used to
collect Javadoc informations on components.
We are aware about the m2Eclipse issue, it's already referenced in  
the FAQ.

Thank you for your feedback. We will check the classes.jar issue.

Hi,

I am using maven from eclipse (It did not worked) but apparently  
launching
it from is fine.

This is the printout of the tld file:

Hi Alessio,

Thanks for your tests.

which Maven version did you use ?


mvn -version
Apache Maven 2.2.0 (r788681; 2009-06-26 15:04:01+0200)

Java version: 1.6.0_20
Java home: /System/Library/Frameworks/JavaVM.framework/Versions/ 
1.6.0/Home
Default locale: en_US, platform encoding: MacRoman
OS name: "mac os x" version: "10.5.8" arch: "x86_64" Family: "mac"


Additionally,
I noticed also a strange behavior using m2eclipse:

I downloaded the source code for the plugin that you provide
Modified the pom.xml to remove the dependency on tools.jar
The build fails because of a failing test:


------------------------------------------------------------------------------

      at

.exanpe 
.tapestry 
.tldgen 
.taglib 
.builder 
.StructureBuilderTest.testHeritage(StructureBuilderTest.java:49)

It seems that attributes of class SubSubComponent are not present.

However,  THE SAME TEST CLASS passes THE SAME TEST when launched  
using
JUnit.

I think one of the problem could be the fact that classes.jar (that  
is a
super set, i.e. contains more classes, of tools.jar) has
"AccessRestrictions" ... unfortunately, I do not know how to deal  
with this.
