Good day to you, Sha Jiang, You may be running your maven2 in jdk1.5, but the plugins that uses java may not necessarily use 1.5.
For example, you can set the maven-compiler-plugin (which by default, handles the compile phase of your build) to a different JVM ( see [1] ) or by specifying the source and targets ( see [2] ). Furthermore, you can also specify the JVM that you will use for the maven-surefire-plugin (which by defaults, handles the test phase of your build) ( see [3] ). Cheers, Franz [1] http://maven.apache.org/plugins/maven-compiler-plugin/examples/compile-using-different-jdk.html [2] http://maven.apache.org/plugins/maven-compiler-plugin/examples/set-compiler-source-and-target.html [3] http://maven.apache.org/plugins/maven-surefire-plugin/test-mojo.html#jvm jiangshachina wrote: > > Hi, >> otherwise it defaults to 1.4 classes with the 1.5 JRE. > I'm using JDK1.5.0_08, but Maven uses 1.3, but 1.4, as default. > > a cup of Java, cheers! > Sha Jiang > > > Wayne Fay wrote: >> >> Yes, to compile 1.5 classes, you must use a 1.5 (or greater) JRE.
