Increase memory of tomcat7 maven plugin?

Question

I want to start an embedded tomcat7 instance directly from maven using the tomcat7-maven-plugin. This is working fine, but the Tomcat started doesn\'t seem to have enough me

Answer 1

You can set the properties in this way

<configuration>
  <systemProperties>
    <JAVA_OPTS>-Xms256m -Xmx512m -XX:MaxPermSize=256m</JAVA_OPTS>
  </systemProperties>
</configuration>

Answer 2

This one worked for me:

<plugin>
    <groupId>org.codehaus.cargo</groupId>
    <artifactId>cargo-maven2-plugin</artifactId>
    <version>...</version>
    <configuration>
        <container>...</container>
        <configuration>
            <type>standalone</type>
            <home>...</home>
            <properties>
                <cargo.jvmargs>-Xmx4096m</cargo.jvmargs>
            </properties>
        </configuration>
        <deployables>...</deployables>
    </configuration>
</plugin>

It starts up my tomcat8 in a new JVM with argument "-Xmx4096m".

Answer 3

As most said in the comments above the properties in pom.xml has no effct. What worked for me was setting my MAVEN_OPTS

MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=256m"

Or on Windows in a cmd terminal:

set MAVEN_OPTS=-Xmx512m -XX:MaxPermSize=256m

For mac/linux users, just add an export statement to your ~/.profile (or similar file name). For example:

export MAVEN_OPTS="-Xmx512m -XX:MaxPermSize=256m"

And restart your shell.
