is there an easy way to run make clean?

I was getting compilation errors and after running clean the compile worked. But there's probably an easier way to do it than what I did. I added another line with ' clean' to this shell script I use to build: $ cat build.sh env -i PATH=/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin \ make \ ALT_BOOTDIR=/usr/local/soylatte16-i386-1.0.3/ \ ALT_FREETYPE_HEADERS_PATH=/usr/X11R6/include \ ALT_FREETYPE_LIB_PATH=/usr/X11R6/lib \ ALT_JIBX_LIBS_PATH=/Users/stephen/dev/java/jibx/lib \ ANT_HOME=/usr/share/ant \ NO_DOCS=true \ HOTSPOT_BUILD_JOBS=1 and ran source build.sh
