> This is more a development environment issue than a bug in IvyDE.=20
> The JDT compiler settings in the {{org.apache.ivyde.eclipse}} plugins are=
 explicitly configured to compile for Java 1.2 (option "Generated .class fi=
les compatibility").
> When exporting that plugin (or the feature), eclipse uses ant to compile =
the plugin, which happens to use the default javac compiler instead of the =
eclipse Java compiler. The Sun/Oracle compilers have a little problem with =
target < 1.4, leading to a {{NullPointerException}} at runtime in SettingsS=
etupEditor.java.
> The issue in SettingsSetupEditor is it creates an anonymous subclass of {=
{PathEditor}}, reimplementing its createText() method. That method is direc=
tly called in the PathEditor constructor. Inside the createText() reimpleme=
ntation, you access fields from the outer instance SettingsSetupEditor (err=
orDecoration, settingsTextDeco). With target 1.2 or 1.3, the other instance=
 is not available though:

> I suggest changing the target to 1.4 to avoid these problems or somehow e=
nsure that the plugin gets always compiled with the eclipse java compiler, =
even on PDE export.
