restore the deleted files in eclipse

I recently did a great job by deleting a class file that's not yet committed to SVN. Thanks to Eclipse I was able to retrieve it using. If you want to restore/undelete files you deleted from Eclipse, all you have to do is to right-click on the folder and choose "Restore from local history".

the style 'backgroundalpha' is only supported by type 'mx.controls.textInput' with the theme(s) 'halo'

When I created a new project on Flash Builder 4.5 and imported an old project to this space, I saw that there are a dozen of errors. All of them are "The style 'backgroundAlpha' is only supported by type 'mx.controls.TextInput' with the theme(s) 'halo'". I remember there was no error with the project so I googled to see the problem and it seems like flex does not have this style as of version 4. But our project was in flex 3 and I remember not setting the flex version explicitly when I created the project. Flash builder automatically added this version (flex 4)  to libraries and thus the old project code stopped working. When I switched back to flex 3, it began working again. To achieve this, I clicked on the project > properties > Flex Build Path and chose flex 3.

packaging with value jar is invalid ?

While trying to build my new project using maven, I got "packaging' with value 'jar' is invalid" error.
I have a parent pom and a separate pom in each modules' folder; but in none of my pom files, I set packaging as "jar".

After googling a little, I saw that the default packaging is "jar" and in the parent pom I didn't specify any packaging type.
So it uses "jar" as packaging type of the parent which is wrong.
After adding "<packaging> pom <packaging>" to my parent pom's attributes, the maven error is gone.
