You need to use 2.0.9 and then the order will be consistent. In the past
we didn't use linked collections so it was subject to the natural
ordering, which changed between 1.5 and 1.6. In 2.0.9, the order as
defined in the pom is preserved so you can reorder if you want to tweak
the resolution. All other things being equal (depth, scope etc) Maven
prefers the version found first.

Subject: Compiled dependencies are different when using different java
versions

Hi All,

 

I've got a problem consistently resolving a project transitive
dependency when using different java versions. In my project xercesImpl
is defined as a transitive dependency for two artefacts:

 

Project

+- dependency1

|  +- xerces:xercesImpl:jar:2.6.2:compile

+- dependency2

|  +- xerces:xercesImpl:jar:2.8.1:compile

 

In this situation i'm not sure which version is included in compilation.


 

However what I didn't expect was that if I switch JDK versions between
jdk1.5.0 and jdk1.6.0 that what is compiled would be different!

 

Below is the dependency tree when run on the same machine, with the same
settings, but with different JAVA_HOME variables set.

 

 

 

Java 5

 

> mvn -version

 

Maven version: 2.0.7

Java version: 1.5.0_08

OS name: "windows xp" version: "5.1" arch: "x86"

 

> mvn dependency:tree

 

...

[INFO] +- jaxen:jaxen:jar:1.1.1:compile

...

 [INFO] |  +- xerces:xercesImpl:jar:2.6.2:compile

...

 [INFO] \- caplin.datasource:datasource-java:jar:4.4.8:compile

 

 

Java 6

 

> mvn -version

 

Maven version: 2.0.7

Java version: 1.6.0

OS name: "windows xp" version: "5.1" arch: "x86"

 

> mvn dependency:tree

 

...

[INFO] +- caplin.datasource:datasource-java:jar:4.4.8:compile

[INFO] |  \- xerces:xercesImpl:jar:2.8.1:compile

...

[INFO] +- jaxen:jaxen:jar:1.1.1:compile
