[ 310s] /usr/src/packages/BUILD/bundles/org.eclipse.swt/buildFragment.xml:61: Compile failed; see the compiler error output for details.The default encoding is US-ASCII. Some packages contain characters that cannot be displayed with the default encoding and thus will cause build failures. Set encoding to UTF-8 to fix this error.
