Hi Sean Patrick Floyd,


Yes i tried using maven-antrun-plugin but i am not able to setup JDK 1.4.2 version in it. I am trying to specify all possible way to apply JDK version 1.4.2 but it's still taking tools.jar or JDK version, Which maven.bat file is using (jdk 1.5)

I was using following code in MAVEN-ANTRUN-PLUGIN as below code.

<plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-antrun-plugin</artifactId>
                <version>1.6</version>

                <executions>
                    <execution>
                        <id>install</id>
                        <phase>install</phase>
                        <goals>
                            <goal>run</goal>
                        </goals>
                        <configuration>
                            <source>${java-version}</source>
                            <target>${java-version}</target>
                            <compilerVersion>${java-version}</compilerVersion>
                            <ex开发者_Python百科ecutable>${java.1.4.2.home}/bin/javac</executable>
                             <target>

                                <property name="plugin_classpath" refid="maven.plugin.classpath" />
                                <property name="maven_dependency_classpath" refid="maven.dependency.classpath" />
                                <ant antfile="ant_build.xml" />
                             </target>
                      </configuration>
                    </execution>
                </executions>
                <dependencies>
                    <dependency>
                        <groupId>sun.jdk</groupId>
                        <artifactId>tools</artifactId>
                        <version>1.4.2</version>
                        <scope>system</scope>
                        <systemPath>${java.1.4.2.home}/lib/tools.jar</systemPath>
                    </dependency>
                    <dependency>
                        <groupId>com.sun</groupId>
                        <artifactId>rt</artifactId>
                        <version>${java-version}</version>
                        <scope>system</scope>
                        <systemPath>${java.1.4.2.home}/jre/lib/rt.jar</systemPath>
                    </dependency>
                </dependencies>
            </plugin>



That's why i choose exec GOAL where my SYSTEM JAVA_HOME is 1.4.2 and it's able to execute it if i have all dependencies which i needed.


Please help me out.






Thanks.

maven.plugin.classpath etc. are variables defined in the maven-antrun-plugin only. The exec plugin doesn't know about these values. Also, it wouldn't be possible to do it like that in the first place, as you are calling an external .bat file and hence starting a new process.

If I were you I'd use the antrun plugin. See the usage page for details.

Update: ok, now I see your problem. No, you can't use a different JDK, since antrun works within the same vm. So either you need to switch the JDK maven uses, or you do in fact need to use the exec-maven-plugin. In the latter case, you will have to use
dependency:build-classpath -DoutputFile=someFile.txt
and on the ant side, read the contents of someFile.txt as a property and create a classpath from it. Or you can use the %classpath variable placeholder in your command line args.

Yes correct answer which i found is to Use MAVEN version which supports JDK 1.4.2. So i have to use apache-maven-2.0.11 which supports JDK 1.4.2

Thanks all for your answers.
