my compiler plugin is configured like that

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.4</version>
            <configuration>
                <source>1.7</source>
                <target>1.7</target>
            </configuration>
        </plugin>

i already tried to set

MAVEN_OPTS=-Xmx1024m

in my windows7

why can eclipse compile this file but maven not?

Answer 1

Your problem is not Maven but the Java compiler itself. But even if the compiler would not crash you will quite likly exeed the class file's code_length of 64 KiB.

I suggest splitting the Java source into multiple source files.
