PDE Gurus,
Session info:
eclipse.buildId=4.16.0.I20200604-0540
java.version=1.8.0_232
java.vendor=Oracle Corporation
BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=en_US
Framework arguments: -product org.eclipse.epp.package.rcp.product -showlocation main
Command-line arguments: -os linux -ws gtk -arch x86_64 -product org.eclipse.epp.package.rcp.product -clean -showlocation main -data workspace.plugin
OS Info:
CentOS 7 - 3.10.0-1062.9.1.el7.x86_64
Problem:
I've been making some changes to our local Eclipse plugin recently, and exporting it via File->Export...->Plug-in Development->Deployable plugins and fragments.
This mechanism works a few times, but usually within three or so exports I'll start getting a panel that says:
'Export Plug-ins' has encountered a problem.
Could not find one or more classes:
"org.eclipse.ant.internal.core.ant.InternalAntRunner".
Please check the Ant classpath.
Once this starts happening then the export doesn't work again until I restart Eclipse.
The error log shows the exception at the bottom of this message.
Any clue what might be causing this?
Rob
