Use the links below to download the Apache Flex® SDK from one of our mirrors. You must verify the integrity of the downloaded files using signatures downloaded from this page.
Only current recommended releases are available on the main distribution site and its mirrors. Previous releases produced by Adobe, including 4.6.0 are available at Adobe's Sourceforge Site.
The Apache Flex® SDK has some compile-time dependencies. Please make sure to review the dependencies section if you plan on compiling the source from scratch.
Please review the release notes before installing or compiling the SDK.
The Apache Flex team is pleased to offer this release, available as of 28th October 2013. This is the lastest Apache Flex SDK release and is designed to be compatible with previous versions of the Apache Flex SDK and Adobe Flex SDK.
You can always grab the "in-development" version of our code. Things may not work, nor may tests pass. Use at your own risk.
If you are looking for the cutting edge development branch of the Flex SDK:
git clone https://git-wip-us.apache.org/repos/asf/flex-sdk.git sdk cd sdk git checkout develop You will also need: git clone https://git-wip-us.apache.org/repos/asf/flex-tlf.git tlf See the README at the root of the sdk for further details on how to set it up.
Due to licensing requirements, there are some components that we depend on that we can not include in our binary or source distribution. We try our hardest to limit these dependencies, however for the current 4.11.0 release we do depend on the following components. Please review the README included in your download for more information on where to install these packages.
The following dependencies are optional, and if available will provide additional features to the Flex Framework:
Embedded Font Support:
All of the above dependencies can automatically be downloaded via the following ANT command :
cd <flex.dir>/frameworks ant thirdparty-downloads
If you are planning on compiling the source code, you will need the following components. More details are available in the README file in the downloaded package. Some of these components have licenses that differ from the Apache License.
Apache relies on 3rd party mirrors to distribute their software. Because these releases are hosted on servers that are not under our control, we strongly recommend that you verify the integrity of the binaries or source code before you install it using the PGP or MD5 signatures listed next to the downloads. This involves a few extra steps, but it will verify that you are getting a true Apache release.
The PGP signatures can be verified using PGP or GPG. First download the KEYS as well as the asc signature file for the relevant distribution. Make sure you get these files as linked from this page (rather than a mirror) to insure the integrity of the files.
% pgpk -a KEYS % pgpv apache-flex-sdk-4.11.0-src.tar.gz.asc
% pgp -ka KEYS % pgp apache-flex-sdk-4.11.0-src.tar.gz.asc
% gpg --import KEYS % gpg --verify apache-flex-sdk-4.11.0-src.tar.gz.asc
Alternatively, you can verify the MD5 signature on the files. A unix/Mac program called
md5sum is included in many unix distributions. It is also available as part of GNU Textutils. Windows users can get binary md5 programs from here , here , or here. An MD5 signature consists of 32 hex characters, and a SHA1 signature consists of 40 hex characters. Ensure your generated signature string matches the signature string published in the files above.
