maven java:compile

hi folks,

i'm trying to compile and run a simple project found on the web to go on, following structure:

c:\daven
-.. src
-...... java
-............. smartsoft
-........................... daven
-..................................... Box.java
-project.xml

and setting environment variable done confirming:

C:\Documents and Settings\Solar>mvn --version
Apache Maven 2.2.1 (r801777; 2009-08-06 12:16:01-0700)
Java version: 1.6.0
Java home: C:\Program Files\Java\jdk1.6.0\jre
Default locale: en_US, platform encoding: Cp1252
OS name: "windows xp" version: "5.1" arch: "x86" Family: "windows"

depending on what i read on web to compile the only thing is to change to the directory and typing:
maven java:compile

with this 'm gettin:
C:\Documents and Settings\Solar>maven java:compile
'maven' is not recognized as an internal or external command,
operable program or batch file.

changing this command to:
mvn java:compile

C:\Documents and Settings\Solar>mvn java:compile

what is this? how can i compile and run? what jar(s) and where to get/put them i need?

best regards...

Your JAVA_HOME is set incorrectly, it should be "C:\Program Files\Java\jdk1.6.0"

You are using Maven 2, but the directory structure is not a standard Maven 2 structure (it looks like a Maven 1 project). You should have this (assuming c:\daven is the project's base directory, and smartsoft.daven.Box is the class' full package name)

c:\daven\
+ pom.xml
+ src\java\main\smartsoft\dave\Box.java

In addition, to build the app you need run only:

mvn

I think that your are getting Maven 1 and Maven 2 instructions mixed up. Here are some good Maven 2 guides:
http://www.maestrodev.com/better-build-maven
http://www.sonatype.com/products/maven/documentation/book-defguide

First and last it’s an honor hearing from you, so purely thank you,

Peter Johnson wrote:Your JAVA_HOME is set incorrectly, it should be "C:\Program Files\Java\jdk1.6.0"

well, I don’t know what is this ‘JAVA_HOME ... jre’ for, in fact tried to set environment variable by:
System Properties > Advanced > Environment Variables > (User, System) Variable like:

System Variable:
JAVA_HOME=C:\Program Files\Java\jdk1.6.0
MAVEN2_HOME= D:\apache-maven-2.2.1
Path=.....; %MAVEN2_HOME%\bin;%JAVA_HOME%\bin;

but I’m getting like that peculiar JAVA_HOME ... jre form!!!

what is this odd don’t know and lead me to this result:

C:\Documents and Settings\Solar>mvn --version
Apache Maven 2.2.1 (r801777; 2009-08-06 12:16:01-0700)

...

Oh thank you! very nice sites, then i’ll try them fist, so we have Chapter 3. A Simple Maven Project:

mvnexbook-examples-0.3.1\ch-simple\
D:\simple\
+pom.xml
+src\mainjava
+src\test\java

3.3. Building a Simple Project
@echo off
set JAVA_HOME="C:\Program Files\Java\jdk1.6.0"
set MAVEN2_HOME="D:\apache-maven-2.2.1"
set PATH=%PATH%;%JAVA_HOME%\bin;%MAVEN2_HOME%\bin
cd D:\simple
mvn install
pause

but bat don’t stand still to show at least Press any key to continue . . ., no result

, even when you wanna check maven per se (e.g. mvn -v),

best regards

Regarding "jre", I now understand. You originally posted the result of "mvn --version" which adds the 'jre' to JAVA_HOME. Apparently I was not paying close enough attention. Your setting is correct.

Do this. Open a Command Prompt, cd to the project directory (c:\simple), and enter:

mvn package

Then post the full output that appears on the command prompt.

but bat don’t stand still to show at least Press any key to continue . . .

Of course it will not pause. 'mvn' is actually 'mvn.bat'. When one batch file calls another, the first batch file stops processing and there is no "return". If you want the first batch file to continue to run after the second batch file finishes, you must use the "call" command:

no result

Are you sure? Did you check the c:\simple\target directory?

very robust message

, on your command here it is the full prompt:

Looks fine.

But, I found what is going wrong !!

C:\Documents and Settings\Solar>cd D:\simple

C:\Documents and Settings\Solar>mvn install

On windows, when you type cd D:\simple from a directory which is on another disk (here, C

, it doesn't work. You should before change the disk by simply typing its letter in the command prompt.

try this :

C:\Documents and Settings\Solar>D:

D:\>cd simple

D:\simple>mvn install

should work fine now ;)

Evan and A., I will have to ask you to either remove your foreign language posts or replace them with the English translation - Java Ranch has a strict English-only policy. Thank you for your cooperation.

[I removed the posts...]

Ok Peter, sorry for that

yes, at full tilt you’re right it’s the place merely, and this is what I like about you telling rules frankly,
and I like to obey rules, an’ thank you no less, I know I’m novice here with mistakes that time would make it profound.

Titina (Je Cherche Après Titine)
Lyrics by Bertal-Maugon and E. Ronn, Music by Léo Daniderff
Copyright ©1922/1925/1963 Warner Music

I've always been a restless rover, in search of femininity.
I've met the pretty girls all over, but only one appealed to me.
My loving heart I gayly tossed her, this Spanish kid in old Madrid,
She captured me and then I lost her, and ever since I'm off my lid.
I never will forget her face,
I'm searching for her ev'ry place.

I'm looking for Titina, Titina, my Titina,
I've searched from Palistina, to London and Peru.
I'll die without Titina, I can't eat my farina,
I don't want Rose or Lena, Titina I want you.
Ah! Mama! Ah! Papa!
