Hi,
I tried giving JRE and TOOLS JAR from build.xml file. But it's working fine
if i run as ANT script.
But when i execute as MAVEN it's taking JAVA_HOME variable which is setup as
system variable so my system JAVA_HOME is 1.5 and i want to compile with
1.4.2 from MAVEN Only.
Even i gave dependencies as below.
<dependencies>
<dependency>
<groupId>sun.jdk</groupId>
<artifactId>tools</artifactId>
<version>1.4.2</version>
<scope>system</scope>
<systemPath>${java.home}/lib/tools.jar</systemPath>
</dependency>
<dependency>
<groupId>com.sun</groupId>
<artifactId>rt</artifactId>
<version>1.4.2</version>
<scope>system</scope>
<systemPath>${java.home}/jre/lib/rt.jar</systemPath>
</dependency>
</dependencies>
And Also tried giving something like this.
<configuration>
<javaHome>${java.home}</javaHome>
<source>${java-version}</source>
<target>1.4.2</target>
</configuration>
But it's still taking JDK 1.5 while compiling the source Code.
Please advice me.
Thanks,
daivish.
