Using the test program with a makefile.

[lil_panda]

I am using a make file to build my java project.
The code in my makefile is:

INSTALLPATH=/usr/bin

all:
	@echo "Compiling all source files to bin/"
	@ant

clean:
	@echo "Cleaning all targets"
	@ant clean

install:
	if (! test -e dist/jar.jar ) then
		@make all
	fi
	@echo "Installing in ${INSTALLPATH}"
	cp dist/*.jar ${INSTALLPATH}

and when i run make install I get this error:

if (! test -e dist/jar.jar ) then
/bin/sh: -c: line 1: syntax error: unexpected end of file
make: *** [install] Error 2

What am I doing wrong?
