如何以编程方式检查是否启动了eclipse控制台构建或GUI构建？

Question

I am writing CDT plug-in for Eclipse IDE. I want to show a warning dialog to user if GUI Eclipse instance is launched, otherwise if console build is launched just write to stderr. How can I determine programmatically which of GUI and console Eclipse is launched?

Answer 1

UPDATE: This code works properly only if a corresponding system property is set.

boolean isHeadless = System.getProperty("eclipse.application")
            .equals("org.eclipse.cdt.managedbuilder.core.headlessbuild");

This code checks an argument passed as an "application", it is "org.eclipse.cdt.managedbuilder.core.headlessbuild" in case of a headless eclipse launch.

You could also check SWT plugin's state:

Bundle swtBunble = Platform.getBundle("org.eclipse.swt");
boolean isHeadless = (swtBunble==null || swtBunble.getState() != Bundle.ACTIVE);
