Hi
I recently started using Maven, and I will hopefully be implementing in for
every single project I start from now on :-)
However, I have some issues when building one of my gwt projects.
I get an error like this
[INFO] Compiling 1 source file to F:\Data\Workspace\testapp\target\classes
[ERROR]
Mojo:
org.apache.maven.plugins:maven-compiler-plugin:2.0.2:compile
FAILED for project:
maven-test:testapp:war:0.0.1-SNAPSHOT
Reason:
Failure executing javac, but could not parse the error:
javac: source release 1.5 requires target release 1.5
The Mojo plugin looks like this
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.0.2</version>
<configuration>
<source>${maven.compiler.source}</source>
<target>${maven.compiler.target}</target>
<encoding>UTF-8</encoding>
<!-- Fix for GWT issue #3439 -->
<excludes>
<exclude>javax/servlet/**</exclude>
</excludes>
</configuration>
</plugin>
and my properties looks like this
<properties>
<gwt.version>1.6.4</gwt.version>
<maven.compiler.source>1.5</maven.compiler.source>
<maven.target.source>1.5</maven.target.source>
<gwt.output.directory>${basedir}/target/gwt</gwt.output.directory>
<gwt.module.alias>Application</gwt.module.alias>
</properties>
Why does the comiplier think I want to use something else for target than
1.5 ?
