In eclipse we have options like File,Edit,Refactor etc in that list we have Project also click on that Project tab, then you will have Build Automatically option their. – Ankit HTech Mar 11 '13 at 09:30

Open Android SDK Manager.(Windows → Android SDK manager)
Go to Tools → Options.
Click on Clear Cache → Close.
Go to Packages → Reload.

Packages will be visible now under the latest downloads in SDK manager.

I tried most of the things but nothing worked for me. After spending some time i got the solution

Open {Android SDK dir}\build-tools and also open project.properties in our project

Check for sdk.buildtools=29.0.0 (If you don't have this, just add it manually) Change 29.0.0 entry based on {Android SDK dir}\build-tools folder and start the build

Ex:

{Android SDK dir}\build-tools i have 28.0.3. Then I've changed sdk.buildtools=28.0.3 gave the build. Not worked
{Android SDK dir}\build-tools i have 25.0.3. Then I've changed sdk.buildtools=25.0.3 gave the build. Not worked
{Android SDK dir}\build-tools i have 24.0.3. Then I've changed sdk.buildtools=24.0.3 gave the build. Success

The only solution worked for me was removing the impacted versions from build tools folder.
