Eclipse – Technical Notes

There are many cases nowadays when you have to go through HTTP proxy in order to access the internet. Eclipse provides an option to configure HTTP proxy settings – either by manual configuration or loading native system settings. (It does not support auto-configuration scripts, though, so if this is the way you configure your OS, you’ll have to provide proxy address to Eclipse manually.)

However. the settings configured via Eclipse preferences are not propagated to the Java programs that you develop. Obviously, you can provide proxy settings via VM arguments, but doing that for each and every run configuration may be painful. Fortunately, this can be solved with the help of “Default VM Arguments” setting under JRE/JDK definition. System properties configured there will be in effect for every Java program you are going to run or debug. Continue reading “Eclipse: Configure HTTP Proxy Settings for All Run Configurations” →

Unlike the early Eclipse days, now most of Eclipse plugins are distributed via Update Manager. Installation of new software is only a few clicks away – unless your development environment is not connected to the internet! Some vendors publish update site archives for offline use, but most of them are not. Eclipse tries to provide a solution for that with site mirroring, but is not as easy as it could be and forces you to install full-fledged Eclipse on a machine connected to the internet. So, what can you do about it?

Let’s take run-jetty-run – excellent plugin that allows you to run Jetty in Eclipse with a single click, including source attachment for debugging, – and prepare an offline update site for it. Continue reading “How to Download Eclipse Update Site for Offline Use” →
