STS 2.5.2 Error Message during save/build

[Slidewayz]

Hi,

I have a Mac Snow Leopard and am using STS 2.5.2 Carbon w/the Flex 4 plugin.

When I am in the Flex perspective, there is no problem.

However, when I am in the Java perspective, any time I save a Java class I get the follow error:

'Errors occurred during the build'

Building Spring AOP reference model
Building workspace

The 'Details' message:

Errors occurred during the build.
Errors running builder 'Spring Project Builder' on project 'My_Project'.
java.lang.NullPointerException

...any help further diagnosing the problem or fixing it would be most appreciated. I can still save/build and run the project, but it is irritating to have to clear this error with 'OK' (no, it isn't) every time I save.

Thanks !

Hi,

could take a look at your Error Log. There should be more information about this NPE available. Let me know what you find and I take a look at asap. This shouldn't be too hard to fix.

[Christian Dupuis]

Hi,

the NPE is fixed in latest STS 2.6.0.M1. Would it be possible for you to update to this version? You can use the following update site to install the M1: http://dist.springsource.com/milesto...S/update/e3.5/ for Eclipse 3.5 or http://dist.springsource.com/milesto...S/update/e3.6/ for Eclipse 3.6.

The ClassNotFoundException seems to be an issue with an incomplete project classpath. Can you tell me what version for Spring Flex you are using and if you're using Maven could you provide your pom.xml? If you don't use Maven could you provide the .classpath file?

Thanks, Christian

[Slidewayz]

I will try the upgrade to STS 2.6.0.M1 and let you know how it works.

Spring-Flex 1.0.3-Release

I do not use Maven.

Where do I find the .classpath file on Snow Leopard ?

Thanks again !!!
