This is my first post on this forum. I have a problem with Maven 3. OS: Windows 8 Professional RTM.
If I run any maven command (whatever) I always get the following answer:
Usage: java [-options] class [args...] (to execute a class) or java [-options] -jar jarfile [args...] (to execute a jar file)
where options include: -server to select the "server" VM -hotspot is a synonym for the "server" VM [deprecated] The default VM is server.
-cp <class search path of directories and zip/jar files> -classpath <class search path of directories and zip/jar files> A ; separated list of directories, JAR archives, and ZIP archives to search for class files. -D<name>=<value> set a system property -verbose[:class|gc|jni] enable verbose output -version print product version and exit -version:<value> require the specified version to run -showversion print product version and continue -jre-restrict-search | -jre-no-restrict-search include/exclude user private JREs in the version search -? -help print this help message -X print help on non-standard options -ea[:<packagename>...|:<classname>] -enableassertions[:<packagename>...|:<classname>] enable assertions -da[:<packagename>...|:<classname>] -disableassertions[:<packagename>...|:<classname>] disable assertions -esa | -enablesystemassertions enable system assertions -dsa | -disablesystemassertions disable system assertions -agentlib:<libname>[=<options>] load native agent library <libname>, e.g. -agentlib:hprof see also, -agentlib:jdwp=help and -agentlib:hprof=help -agentpath:<pathname>[=<options>] load native agent library by full pathname -javaagent:<jarpath>[=<options>] load Java programming language agent, see java.lang.instrument -splash:<imagepath> show splash screen with specified image
I used Google and forum search but the only results were a different problem: it was a problem on environment variables (most of them ending the path with an additional slash).
If I execute java -version I get:
java version "1.6.0_35" Java(TM) SE Runtime Environment (build 1.6.0_35-b10) Java HotSpot(TM) 64-Bit Server VM (build 20.10-b01, mixed mode)
If I execute javac -version I get:
javac 1.6.0_35
The Maven verssion I am using is 3.0.4. These are the environment variables I added (I added M2_HOME and MAVEN_HOME because I am not sure about which one is the right variable):
CATALINA_OPTS=%MAVEN_OPTS%
CLASSPATH=%JAVA_HOME%\src.zip;%JAVA_HOME%\lib\tools.jar;
JAVA_HOME=C:\Program Files\Java\jdk1.6.0_35
M2_HOME=d:\software\apache-maven-3.0.4
MAVEN_HOME=d:\software\apache-maven-3.0.4
MAVEN_OPTS=-Xms512m -Xmx1024m -XX:PermSize=256m -XX:MaxPermSize=512m
PATH=%JAVA_HOME%\bin;%MAVEN_HOME%\bin;d:\software\eclipse;%M2_HOME%\bin
The path environment variable has more paths but I just pasted here the paths I added for my final year project.
Thanks in advance for your help.
The only environment variables you need to set are:
JAVA_HOME=C:\Program Files\Java\jdk1.6.0_35
MAVEN_HOME=D:\software\apache-maven-3.0.4
PATH=%PATH%;%MAVEN_HOME%\bin;%JAVA_HOME%\bin
Note, use D: instead of d:
