Negative seek offset Exception while deploying an ext-plugin via Lfr-IDE

[Oliver Bayer, modificado 12 Anos atrás.]

Hi all,

I'm using the newest Liferay IDE and 6.0.6 SDK with current svn trunk at revision 91397. Without any other modifications I've created a new ext plugin and added only some properties to portal-ext.properties. While deploying the ext plugin via drag&drop and then starting the server the following exception is thrown in console:

The portal-ext.properties is nevertheless deployed and the changes (e.g. using another db...) are applied too. So it's not that big issue but maybe someone (like Greg ) knows a good workaround without throwing exceptions.

The exception is coming due to processing of a zip file, kinda like you may have some sort of corrupted file in your ext plugin deployment artifact...

I'd track down the corrupted file before pointing a finger at Greg and saying it's the Liferay tool chain causing the problem...

Hey Oliver,

If you could send me the source to your EXT plugin I can try to replicate on my side, along with the version of IDE you are using.

Hi,

thanks for your responses.

@David:
No need to defend Liferay or Greg or both because I've only found a possible bug and reported it. Nothing more nothing less - don't shoot the reporter .

@Greg:
I've done the following steps as the exception occurred:
1. unzipped Liferay 6.1.0-b3
2. deleted all in webapps folder beside ROOT and tunnel-web
3. deployed the mentioned svn code revision
4. created an ext plugin using Liferay IDE v1.4.0.v201110020918 and 6.0.6 SDK
5. as mentioned above I've only added a few keys to portal-ext.properties
6. after deploying the ext to server with the IDE via drag&drop the zip exception occurred

You can use the attached zip of my ext as a reference.

Thanks in advance.

Hello,

I have the same problem. The only difference with the steps Oliver describes is that I use the 6.1.0-b3 SDK instead of the 6.0.6 SDK.
I also have that problem with the 6.1.0-b4 bundle + sdk.

Hi Sébastien,

thanks for the info - so at least I'm not the only one .
Now we have to hope that Greg will find and fix the issue with the upcoming IDE version.

Hey guys,

I'm going to try to replicate and take a look at this problem for next release of IDE:

Hi Greg,

thanks for the update.

How to reslove the "Negative Seek Offset" issue. Sometimes, Action Classes overridden are not deployed because of this error.
