Hello to the Maven users.
I am trying to generate two artefacts, each containing two different flavours
of generated classes.
I am able to generate the classes under two different folders:
target\generated-sources-jacorb
target\generated-sources-sunorb
Now I would like to compile these two folders separately in the same build, and
include them in two different artefacts.
I am using the following configuration, with two executions
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<executions>
<execution>
<id>compile-with-jacorb</id>
<goals>
<goal>compile</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/classes-jacorb</outputDirectory>
<excludes>
<exclude>**/generated-sources-sunorb/*</exclude>
</excludes>
</configuration>
</execution>
<execution>
<id>compile-with-sunorb</id>
<goals>
<goal>compile</goal>
</goals>
<configuration>
<outputDirectory>${project.build.directory}/classes-sunorb</outputDirectory>
<excludes>
<exclude>**/generated-sources-jacorb/*</exclude>
</excludes>
</configuration>
</execution>
</executions>
</plugin>
however the compilation fails with the error
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile)
on project test-attach-artifact: Compilation failure: Compilation failure:
[ERROR]
\dev\Projects\test-attach-artifact\target\generated-sources-jacorb\idl\uk\co\igindex\corba\service\V3_0\NoDataHelper.java:[11,13]
duplicate class: uk.co.igindex.corba.service.V3_0.NoDataHelper
..........
I.e. both generated source folders are included during compilation. I can see
this in the maven output:
[DEBUG] Configuring mojo
'org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile' with basic
configurator -->
[DEBUG] (f) basedir = C:\dev\Projects\test-attach-artifact
[DEBUG] (f) buildDirectory = C:\dev\Projects\test-attach-artifact\target
[DEBUG] (f) classpathElements =
[C:\dev\Projects\test-attach-artifact\target\classes]
[DEBUG] (f) compileSourceRoots =

C:\dev\Projects\test-attach-artifact\target\generated-sources-jacorb\idl,
C:\dev\Projects\test-attach-artifact\target\generated-sources-sunorb\idl]
......
However, looking at the first part of the output (before the above excerpt), it
looks the configuration is picked up
[DEBUG] Goal:
org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile
(compile-with-jacorb)
[DEBUG] Style: Regular
[DEBUG] Configuration: <?xml version="1.0" encoding="UTF-8"?>
<configuration>
<basedir default-value="${basedir}"/>
<buildDirectory default-value="${project.build.directory}"/>
<classpathElements default-value="${project.compileClasspathElements}"/>
<compileSourceRoots default-value="${project.compileSourceRoots}"/>
<compilerId default-value="javac">${maven.compiler.compilerId}</compilerId>
<compilerVersion>${maven.compiler.compilerVersion}</compilerVersion>
<debug default-value="true">${maven.compiler.debug}</debug>
<debuglevel>${maven.compiler.debuglevel}</debuglevel>
<encoding

<excludes>
<exclude>**/generated-sources-sunorb/*</exclude>
</excludes>
.........
and
[DEBUG] Goal:
org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile
(compile-with-sunorb)
[DEBUG] Style: Regular
[DEBUG] Configuration: <?xml version="1.0" encoding="UTF-8"?>
<configuration>
<basedir default-value="${basedir}"/>
<buildDirectory default-value="${project.build.directory}"/>

<compileSourceRoots default-value="${project.compileSourceRoots}"/>
<compilerId default-value="javac">${maven.compiler.compilerId}</compilerId>
<compilerVersion>${maven.compiler.compilerVersion}</compilerVersion>
<debug default-value="true">${maven.compiler.debug}</debug>
<debuglevel>${maven.compiler.debuglevel}</debuglevel>
<encoding
default-value="${project.build.sourceEncoding}">${encoding}</encoding>
<excludes>
<exclude>**/generated-sources-jacorb/*</exclude>
</excludes>
.......
Therefore, I do not understand why the configuration is loaded and then
discarded. If someone could help me, I would really appreciate.
Thanks
