If you are using Oracle JDeveloper and ADF with some version control system, such as Git, here's a minimum list of JDeveloper and ADF specific untracked files and directories you will want to add to your .gitignore file to ignore them:

.data/
temp/
classes/
deploy/
javadoc/
cwallet.sso.lck

The .data/ directory is the application storage directory used by the IDE Performance Cache feature. For each application, you can specify a directory where application-specific caches and indexes used by JDeveloper are stored. To customize the location of the directory, open the Application Properties dialog, then go to the IDE Performance Cache page.

The default location is the root directory of the application:

The temp/ directory is used for ADF styles caching. It gets created under the WEB-INF/ directory in the web content directory of the view project, when you open a page or page fragment in the design mode in JDeveloper.

The classes/ directory is the default Output Directory for the project. It can be customized in the Project Properties dialog, Project Source Paths page.

The deploy/ directory is the default output directory for the archives generated from deployment profiles defined for the project. You can customize it in the Edit Deployment Profile Properties window, like this:

The javadoc directory is the default output directory for javadocs, defined in the Javadoc page of the Project Properties window.

The cwallet.sso.lck file is the lock file for the wallet.sso file which is a part of Oracle Credential Store Framework.

The ignore file list is also useful when you are using Subversion or CVS.

Chinese Summary:

针对 Oracle 的 JDeveloper 和 ADF 的，用于版本控制系统的忽略文件列表。可以添加到诸如 Git 的 .gitignore 文件，或者类似的其它版本控制系统（Subversion 和 CVS）的忽略文件中。
