                    <executable>antscript.bat</executable> <!-- ant -f build.xml build -->

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>${java-version}</compilerVersion>
                            <executable>${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.

Answer 1

maven.plugin.classpath等仅是maven-antrun-plugin中定义的变量。 exec插件不知道这些值。此外，首先不可能这样做，因为你正在调用外部.bat文件，因此开始一个新的进程。

如果我是你，我会使用antrun插件。有关详细信息，请参阅the usage page。

更新：好的，现在我看到了你的问题。不，你不能使用不同的JDK，因为antrun在同一个vm中工作。所以要么你需要切换JDK maven使用，要么你确实需要使用exec-maven-plugin。在后一种情况下，您将不得不使用
dependency:build-classpath -DoutputFile=someFile.txt
在蚂蚁方面，将someFile.txt的内容作为属性读取并从中创建一个类路径。或者您可以在命令行参数use the %classpath variable placeholder中进行操作。

Answer 2

是的，我找到的正确答案是使用支持JDK 1.4.2的MAVEN版本。所以我必须使用支持JDK 1.4.2的apache-maven-2.0.11

感谢大家的回答。

exec-maven-plugin想要将maven.dependency.classpath作为我的EXEC目标中的变量传递
