9 years ago Please try updating to latest version (it's 2.7.5 currently), I've added more logging to this release to help you identify failing page/component class.
From what I see there's a problem parsing the @Import annotation. Could you paste it here?

9 years ago Will do, but my Eclipse didn't find any updates - is the update is still at https://dl.bintray.com/anjlab/eclipse-tapestry5-plugin?

9 years ago Ok, so you must have just updated it because I scanned for a new update in the morning. Not sure if this helps, but with 2.7.5, I get:

9 years ago I need this bit:
@org.apache.tapestry5.annotations.Import(
stylesheet = "index.css")
public class IndexIt happens on opening any Java class. Anyhow, figured it out, the issue is an incompatibility with JRE 1.8. I'm running Eclipse on Java 8 and saw this in the log on startup:

at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)I switched back to running with JRE 1.7.0 and the issue is gone. Looks like this is a problem with Eclipse libraries rather than your plugin (still looking for an Eclipse bug report and/or an updated version of the underlying library).

9 years ago Sorry failed to reply. Works great thanks!
I'm regularly getting a NullPointerException just when I open a .java file for a page in Tapestry5 project. Things still seem to work fine after the initial exception. It seems that this started happening when I updated this plugin or some of the underlying components to a new version. I'm using Luna Service Release 1 (4.4.1), "Tapestry5 Support" version 2.6.3 (basic + additional for Eclipse4) and many other plugins.
