How to include jars in lib into project jar file i

问题:

I'm using some apache HttpClient jars, so I put them in my project's lib directory, when Netbeans compiles the project, it copies the lib and generated a project jar into dist directory, but when I run my project with webstart, I need to copy the project jar and lib into tomcat's ROOT dir, I wonder if Netbeans can generate a project jar that includes all the jars in the lib dir, so I don't have to copy the project jar and the lib dir into tomcat's ROOT dir. Can Netbeans do that ?

回答1:

That's really easy to package every dependent library (*.jar) into one single myProject.jar.

Just follow these steps and you will finally pack every dependent library into single jar. If you are using NetBeans then you can follow exactly or else you need to find your build.xml file in project files.

Follow these steps to edit build.xml

1) Click on Files tab on the left side of the project panel in NetBeans.

2) Double click on the build.xml file and add these lines in it just before </project> line

 <target name="package-for-store" depends="jar">
    <property name="store.jar.name" value="myProject"/>
    <property name="store.dir" value="store"/>
    <property name="store.jar" value="${store.dir}/${store.jar.name}.jar"/>
    <echo message="Packaging ${application.title} into a single JAR at ${store.jar}"/>
    <delete dir="${store.dir}"/>
    <mkdir dir="${store.dir}"/>
    <jar destfile="${store.dir}/temp_final.jar" filesetmanifest="skip">
        <zipgroupfileset dir="dist" includes="*.jar"/>
        <zipgroupfileset dir="dist/lib" includes="*.jar"/>
        <manifest>
            <attribute name="Main-Class" value="${main.class}"/>
        </manifest>
    </jar>
    <zip destfile="${store.jar}">
        <zipfileset src="${store.dir}/temp_final.jar"
        excludes="META-INF/*.SF, META-INF/*.DSA, META-INF/*.RSA"/>
    </zip>
    <delete file="${store.dir}/temp_final.jar"/>
</target>

3) Change value in second line of the code as per your project name which is

<property name="store.jar.name" value="myProject"/> //<---Just value not name

4) Save it and right click on build.xml and choose Run Target and then Other Targets and finally click on Package-for-store

5) And here you done. Now you can go and check just like dist folder there will be a store folder which will be containing your final complete jar including all of your dependent libraries. Now whenever you want to change / add more libraries or so, just follow step 4.

OK, found the answer at the following site : http://arunasujith.blogspot.com/2011/08/how-to-build-fat-jar-using-netbeans.html

Robert Eckstein describes a solution for this problem. You just need to paste the following code to build.xml. The libraries are all found automatically.

Here we go:

<target name="-post-jar">

    <!-- Change the value to the name of the final jar without .jar -->
    <property name="store.jar.name" value="MyJarName"/>

    <!-- don't edit below this line -->
    <property name="store.dir" value="dist"/>
    <property name="temp.dir" value="temp"/>
    <property name="store.jar" value="${store.dir}/${store.jar.name}.jar"/>

    <echo message="Packaging ${application.title} into a single JAR at ${store.jar}"/>

    <delete dir="${temp.dir}"/>
    <mkdir dir="${temp.dir}"/>

    <jar destfile="${temp.dir}/temp_final.jar" filesetmanifest="skip">
        <zipgroupfileset dir="dist" includes="*.jar"/>
        <zipgroupfileset dir="dist/lib" includes="*.jar"/>

        <manifest>
            <attribute name="Main-Class" value="${main.class}"/>
        </manifest>
    </jar>

    <delete dir="${store.dir}"/>

    <zip destfile="${store.jar}">
        <zipfileset src="${temp.dir}/temp_final.jar"
        excludes="META-INF/*.SF, META-INF/*.DSA, META-INF/*.RSA"/>
    </zip>

    <delete dir="${temp.dir}"/>

</target>

1. Go to your build.xml, and add the code right before the closing project tag at the end.

2. Now change the value of the first propertiy field as commented

3. Click Clean & Build, and your jar will be in the dist folder

回答4:

1. check MainClass main file is updated as main file in Properties>run
2. Update Build.xml with following code before project tag closes

<!-- Change the value to the name of the final jar without .jar -->
<property name="store.jar.name" value="MyJarName"/>

<!-- don't edit below this line -->
<property name="store.dir" value="dist"/>
<property name="temp.dir" value="temp"/>
<property name="store.jar" value="${store.dir}/${store.jar.name}.jar"/>

<echo message="Packaging ${application.title} into a single JAR at ${store.jar}"/>

<delete dir="${temp.dir}"/>
<mkdir dir="${temp.dir}"/>

<jar destfile="${temp.dir}/temp_final.jar" filesetmanifest="skip">
    <zipgroupfileset dir="dist" includes="*.jar"/>
    <zipgroupfileset dir="dist/lib" includes="*.jar"/>

    <manifest>
        <attribute name="Main-Class" value="${main.class}"/>
    </manifest>
</jar>

<delete dir="${store.dir}"/>

<zip destfile="${store.jar}">
    <zipfileset src="${temp.dir}/temp_final.jar"
    excludes="META-INF/*.SF, META-INF/*.DSA, META-INF/*.RSA"/>
</zip>

<delete dir="${temp.dir}"/>

3. Properties>packaging> tick all
4. clean and build
5. Upload to server.

Okay, so this is my solution. I too had the problem with my program compiling and running on Netbeans but it failing when I tried java -jar MyJarFile.jar. Now, I don't fully understand Maven and I think this why was having trouble getting Netbeans 8.0.2 to include my jar file in a library to put them into a jar file. I was thinking about how I used to use jar files with no Maven in Eclipse.

It's Maven that compiles all the dependencies and plugins, not Netbeans. (If you can get Netbeans to do this please tell us how.)

[Solved - for Linux] by opening a terminal.

Then

cd /MyRootDirectoryForMyProject

Next

mvn org.apache.maven.plugins:maven-compiler-plugin:compile

Next

mvn install

This will create jar file in the target directory.

MyJarFile-1.0-jar-with-dependencies.jar

Now

cd target

(You may need to run: chmod +x MyJarFile-1.0-jar-with-dependencies.jar) And finally

java -jar MyJarFile-1.0-jar-with-dependencies.jar
