Hi Marius. I think this is related to MCOMPILER-122. (See ComponentCheckerAnnotationProcessor.java). This is required because of http://jira.codehaus.org/browse/MCOMPILER-122. However note that IntelliJ IDEA doesn't honor custom sourcepaths, see https://youtrack.jetbrains.com/issue/IDEA-133120, which means that you need to turn off Annotation Processing in IDEA or IDEA will generate errors while building modules --> ------------------------------------------------------------------------------------------------------------ Vincent Massol’ note I've hit this problem too. I've had to do the following (https://github.com/xwiki/xwiki-commons/blob/master/pom.xml#L762): <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <!-- Lock down plugin version for build reproducibility --> <version>3.2</version> <configuration> <source>1.7</source> <target>1.7</target> </configuration> <executions> <!-- We need custom sourcepaths for our Component Annotation Process work (See ComponentCheckerAnnotationProcessor.java). This is required because of http://jira.codehaus.org/browse/MCOMPILER-122. However note that IntelliJ IDEA doesn't honor custom sourcepaths, see https://youtrack.jetbrains.com/issue/IDEA-133120, which means that you need to turn off Annotation Processing in IDEA or IDEA will generate errors while building modules --> <execution> <id>default-compile</id> <configuration> <compilerArguments> <sourcepath>${project.basedir}/src/main/java:${project.basedir}/src/main/resources</sourcepath> </compilerArguments> </configuration> </execution> <execution> <id>default-testCompile</id> <configuration> <compilerArguments> <sourcepath>${project.basedir}/src/test/java:${project.basedir}/src/test/resources</sourcepath> </compilerArguments> </configuration> </execution> </executions> </plugin> However this isn't perfect. It works in Maven but fails in IDEA (see https://youtrack.jetbrains.com/issue/IDEA-133120). I'm also not sure it works on Windows machines (but that could be fixed with profiles). In addition I've noticed that it runs javac with 2 -sourcepath parameters!

I used window to build xwiki. Here is my configuration. C:\Projects\xwiki-platform>mvn -version Apache Maven 3.3.1 (cab6659f9874fa96462afef40fcf6bc033d58c1c; 2015-03-13T16:10:27-04:00) Maven home: C:\apache-maven-3.3.1 Java version: 1.7.0_65, vendor: Oracle Corporation Java home: C:\Program Files\Java\jdk1.7.0_65\jre Default locale: en_US, platform encoding: Cp1252 OS name: "windows 7", version: "6.1", arch: "amd64", family: "windows" I followed the direction on http://dev.xwiki.org/xwiki/bin/view/Community/Building#HInstallingMaven. I can do clean, but not install. mvn clean install -Dxwiki.checkstyle.skip=true It seems that the components in any modules are not able to be compiled. Do I miss any steps in set up in order to build xwiki? I got the same issue when I try to build the xwiki-common package Thanks Ken On Apr 16, 2015 11:14:02 pm , Marius Dumitru Florea (mari...(a)xwiki.com) Wrote What branch / tag of https://github.com/xwiki/xwiki-platform/ are you building? Did you make any changes (is git status clean) ? Did you configure Maven as per http://dev.xwiki.org/xwiki/bin/view/Community/Building#HInstallingMaven ? What OS are you using? I have no problem building the entire xwiki-platform-wiki module on the clean master branch, using Maven 3.0.4 and Java 7 on Linux (Ubuntu).

I fixed all problems related to build. Except one thing if the module has component codes or components.txt I always got builderror. Please see the attached error log. I think I missed one thing but I don't know yet. Can you help me on this issue.
