Improving Code Assist with JSDT and NJSDoc

[paulvi]

For #7 we should try NJSDoc, that actually depends on JSDT.

Currently there is problem when installing in Eclipse for JEE or STS (that both have latest JSDT):

In Aptana, installation goes, finishes with error (see below), but after restart both JSDT & NJSDoc are in.

When installing JSDT+NJSDoc it's important that JSDT from the update site is used: https://bitbucket.org/nexj/updatesite/raw/default . It might be necessary to first uninstall existing JSDT related plugins. If all else fails try install into Eclipse Classic.

I haven't done testing of compatibility as JSDT+NJSDoc is only used internally so far.

[paulvi]

That is unacceptable, because this way is limiting Eclipse flavors where Nodeclipse can be installed on, or makes installation complicated and not compatible with other tools.
This way can be only used during development, but will not go into 0.4.

Can you take the latest JSDT and fix it every major release or contribute to JSDT project?

[johnpeb]

Of course I would like to contribute this to the JSDT project. However

• JSDT has no active development
• Even if they were willing and able to take my contribution there is a lot of work before the rough edges are worked out

In the short term if my fork of JSDT that uses NJSDoc will be integrated with Nodeclipse then a lot of renaming will have to occur so that it can coexist with JSDT installs

[paulvi]

Other option may be to rename your fork, for example to JSDT2. In such a way, that JSDT and JSDT2 can coexist.
I don't know if it is really feasible. Can you estimate?

[johnpeb]

JSDT2 sounds like a good name. I will send one more email to the JSDT (wtp) mailing list to see if they are interested in merging back in. Failing that we can rename to JSDT2. A problem is I won't have time to work on this until mid or late may.

[paulvi]

OK. Meanwhile we can work on this as option, that is only available on Eclipse without JSDT or with old JSDT.
(That sounds no so good, but we can attach word 'experimental' for that)
By the way, can there be problem if, for example, Eclipse 3.6 user gets JSDT updated this way?

Hello John,

I cloned your nexj/njsdoc-build, nexj/webtools.jsdt.core and nexj/updatesite .
Then I tried to build them, but I got an error that said "Unable to find feature "org.eclipse.license" with version in range [1.0.0,1.0.1)." .
I also cloned standard JSDT from GitHub, and I got the same error.

What is the cause of this error?
What should I do to solve this problem?

Best Regards.

[johnpeb]

I found that feature in this repo: git://git.eclipse.org/gitroot/webtools/webtools.releng.git

[tomotaro1065]

Hi John,

Thanks. I cloned that repository. But I couldn't understand how to use those files.
Is it a tool that is mentioned here ?
I installed the tools from http://download.eclipse.org/webtools/releng/repository into Juno-RCP.
And select [Releng]-[Migrate License Support] menu.
Following messages appeared on the console.

Total number of features found: 3
     Total number of primary features found: 2
     Total number of source features found: 1


The following feature(s) were found ok, and not modified
    Count: 3
    org.eclipse.wst.jsdt.feature
    org.eclipse.wst.jsdt.feature[sourceTemplateFeature]
    org.eclipse.wst.jsdt_sdk.feature


Elapsed processing time : 48 ms

It seems nothing happens. I have still the same error after that when building JSDT.

[johnpeb]

Just for the record, lets continue this on the wtp-dev mailing list at least until it gets to NJSDoc specific stuff: http://dev.eclipse.org/mhonarc/lists/wtp-dev/msg08656.html

Quick link is this https://dev.eclipse.org/mailman/listinfo/wtp-dev

Changed to 0.5, we can't possibly do it within 0.4 cycle
