swing - NetBeans GUI builder cannot find SwingX classes -



swing - NetBeans GUI builder cannot find SwingX classes -

i've been thrown existing software development project using maven in netbeans java project.

i've fetched source blessed git repo freshly installed netbeans 8. if build , run it, runs. :-)

i have edit gui of programme created netbeans gui generator. if seek open gui editor, marks components extends jxpanel invalid, because of next error:

java.lang.noclassdeffounderror: org/jdesktop/swingx/jxpanel ... caused java.lang.classnotfoundexception: org.jdesktop.swingx.jxpanel

i not understand – files swingx-1.6.jar , swingx-beaninfo-1.6.jar in dependencies section of project (without "!"), i've added them libraries manager, , i've added them palette. programme runs, why, why, why can't netbeans gui editor find classes?

what doing wrong?

the next excerpt pom.xml:

<dependency> <groupid>org.jdesktop</groupid> <artifactid>swingx</artifactid> <version>1.6</version> <scope>system</scope> <systempath>${basedir}/lib/swingx-1.6.jar</systempath> </dependency> <dependency> <groupid>org.jdesktop</groupid> <artifactid>swingx.beaninfo</artifactid> <scope>system</scope> <version>1.6</version> <systempath>${basedir}/lib/swingx-beaninfo-1.6.jar</systempath> </dependency>

i'd suggest utilize swingx central maven repository instead of local re-create - suspect there bug or gui editor can not resolve ${basedir}. here setup , works well:

<dependencies> <dependency> <groupid>org.swinglabs.swingx</groupid> <artifactid>swingx-all</artifactid> <version>1.6.5</version> </dependency> </dependencies>

and corresponding java class:
