nio2 and files attributes

Question

Just downloaded and installed NetBeans NetBeans IDE 7.2 (Build 201207171143); Java: 1.7.0_03; Java HotSpot(TM) Client VM 22.1-b02. This is instead of Eclipse with JDK 6/ The main reason is because I ama starting a new project, that will have to access files and attributes (back up utility, including clearing the Archive flags - can anyone share experience?). However, the installation doesn't recognize java.nio.file.attribute, and sets error. Any idea?

I hope this can help:

JDK is bundled with all the product installers and it's recommended that you will use the provided JDK version unless there are any specific issues.

32-bit JDK is located in IDE_HOME\jre directory and is used by the 32-bit product executable.

To run the IDE in 64-bit mode you will need to download and install 64-bit JDK (not JRE) distribution and install it yourself. IDE will find and use it from the registry when you run the 64-bit .exe file (available only for IntelliJ IDEA right now, other products can use the .bat file to run in 64-bit mode).

<product>.exe uses this JDK search sequence:

1. IDEA_JDK / WEBIDE_JDK / PYCHARM_JDK / RUBYMINE_JDK environment variable (depends on the product, WEBIDE_JDK applies to both WebStorm and PhpStorm)

2. ..\jre directory
3. system Registry
4. JDK_HOME environment variable
5. JAVA_HOME environment variable

idea64.exe uses this JDK search sequence:

1. IDEA_JDK_64 environment variable
2. ..\jre64 directory
3. system Registry
4. JDK_HOME environment variable
5. JAVA_HOME environment variable

It’s also possible to start the IDE with <product>.bat file located in the bin directory, it uses the following JDK search sequence:

1. IDEA_JDK / WEBIDE_JDK / PYCHARM_JDK / RUBYMINE_JDK environment variable (depends on the product)
2. ..\jre directory
3. JDK_HOME environment variable
4. JAVA_HOME environment variable

Environment variable must point to the JDK installation home directory, for example:

c:\Program Files (x86)\Java\jdk1.7.0_17

• /create-i4j-log command line switch can be used with the .exe to trace the JDK search sequence and find out why the specific JDK was chosen.
• The actual JDK version used by the IDE can be verified in Help | About dialog (open any project to access the menu).
• Define IDEA_JDK / WEBIDE_JDK / PYCHARM_JDK / RUBYMINE_JDK variable depending on the product to override the default version from IDE_HOME\jre.
• Use Rapid Environment Editor to add/edit the variables, it will detect incorrect paths.
