maven error after importing latest code from github - maven

I get the following after i pull the latest code from the githud repository.
problem encountered while building effective model for org.codehaus.mo
The full description of the error is below.
1 problem was encountered while building the effective model for
org.codehaus.mojo:aspectj-maven-plugin:1.8
[ERROR] 'dependencies.dependency.systemPath' for com.sun:tools:jar must specify an absolute path but is ${toolsjarSystemPath} #
I am using java1.8 and sts 3.6.4

Most likely JAVA_HOME environmental variable points to JDK instead of JRE. Change the environment variable and restart Eclipse.
aspectj-maven-plugin contains following:
<profile>
<id>standardToolsJar-profile</id>
<activation>
<activeByDefault>true</activeByDefault>
<file>
<exists>${java.home}/../lib/tools.jar</exists>
</file>
</activation>
<properties>
<toolsjarSystemPath>${java.home}/../lib/tools.jar</toolsjarSystemPath>
</properties>
</profile>
<profile>
<id>appleJdkToolsJar-profile</id>
<activation>
<activeByDefault>false</activeByDefault>
<file>
<exists>${java.home}/../Classes/classes.jar</exists>
</file>
</activation>
<properties>
<toolsjarSystemPath>${java.home}/../Classes/classes.jar</toolsjarSystemPath>
</properties>
</profile>
<profile>
<id>java8</id>
<activation>
<jdk>1.8</jdk>
</activation>
<properties>
<additionalparam>-Xdoclint:none</additionalparam>
</properties>
</profile>
I think the reason this fails is that activeByDefault will not trigger because java8 profile activation is triggered. file->exists condition will not trigger because of incorrect ${java.home}. ${toolsjarSystemPath} will not get set, and attempt to use it will cause the exception.

Maven - Profile Depending on Property?

I have the following profile below, instead of using activeByDefault I would like to active it through a property instead. I saw this comment (https://stackoverflow.com/a/18890159/1959534) in passing about being able to do so through maven assembly plugin but I couldn't figure out how to specify that. Any input on how to accomplish this?
<project ...>
...
<profiles>
<profile>
<id>myProfile</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<dependencies>
<dependency>
<!-- Extra dependency just for this profile -->
</dependency>
</dependencies>
</profile>
</profiles>
</project>
Figured it out!
Defined a system variable in the project's /.mvn/jvm.config and then changed the activation step to be through property instead of activeByDefault. Then used this tips to throw config out to my .properties file: https://stackoverflow.com/a/14386303/1959534
jvm.config
-Dmy.property=true
pom.xml
<profiles>
<profile>
...
<activation>
<property>
<name>my.property</name>
<value>true</value>
</property>
</activation>
</profile>
</profiles>

Manage maven project version by profiles not by parent

I have a parent tag in pom.xml like this:
<parent>
<groupId>com.de</groupId>
<artifactId>MyApplication</artifactId>
<version>2.5.7-SNAPSHOT</version>
<relativePath>../pom.xml</relativePath>
</parent>
Also I have different profiles:
<profiles>
<profile>
<id>default-environment-settings</id>
<properties>
<app.env>dev</app.env>
</properties>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
</profile>
<profile>
<id>xyz</id>
<properties>
<app.env>profile2</app.env>
</properties>
<activation>
<activeByDefault>false</activeByDefault>
</activation>
</profile>
<profiles>
Now I want that my application's version is managed by profiles not as a global parent so that each profile can have it's private version number.
Did you try this ?
<profiles>
<profile>
<id>default-environment-settings</id>
<properties>
<app.env>dev</app.env>
<projectVersion>1.0-SNAPSHOT</projectVersion>
</properties>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
</profile>
<profile>
<id>xyz</id>
<properties>
<app.env>profile2</app.env>
<projectVersion>1.0</projectVersion>
</properties>
<activation>
<activeByDefault>false</activeByDefault>
</activation>
</profile>
<profiles>
And don't forget to put on your artifact
<version>${projectVersion}</version>
Profiles are not intended to declare POM's versions. If you define profiles as mentioned in eclideria's answer and your parent's POM with:
<groupId>com.de</groupId>
<artifactId>MyApplication</artifactId>
<version>${projectVersion}</version>
it will result in:
[WARNING]
[WARNING] Some problems were encountered while building the effective model for com.de:MyApplication:jar:1.0-SNAPSHOT
[WARNING] 'version' contains an expression but should be a constant. # com.de:MyApplication:${projectVersion}, ...MyApplication directory.../pom.xml, line ..., column ...
[WARNING]
[WARNING] It is highly recommended to fix these problems because they threaten the stability of your build.
[WARNING]
[WARNING] For this reason, future Maven versions might no longer support building such malformed projects.

maven settings custom properties

I'm completely new to Maven. I'm trying to set up a new project such that it doesn't require 20 page long word docs with screenshots to set it up. I've got developers on Macs and PCs, so I need to be able to customize the catalina.home directory as I can't just impose a standard location. I thought I'd do it in the ~/.m2/settings.xml file with the following:
<profile>
<id>my-site-dev</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<catalina.home>/path/to/apache-tomcat</catalina.home>
</properties>
</profile>
However, the documentation here: http://maven.apache.org/guides/introduction/introduction-to-profiles.html#Profile_Pitfalls seems to indicate that what I'm trying to accomplish is a bad idea. What's the official way of accomplishing this so that in my pom.xml I can just reference ${catalina.home}?
And now that I've declared my profile with an id, can I fail the build if my pom.xml can't load the profile "my-site-dev"? I'd like to get that <activeByDefault> out of the settings.xml if at all possible. I don't want to interfere with their global settings for no reason, I'd like to keep as much of it self contained as possible.
Don't use activeByDefault, since it will cloak all other profiles:
Here is what you should use:
<profiles>
<profile>
<id>path-to-catalina.home-linux</id>
<activation>
<os>
<family>linux</family>
</os>
</activation>
<properties>
<catalina.home>...</catalina.home>
</properties>
</profile>
<profile>
<id>path-to-catalina.home-mac</id>
<activation>
<os>
<family>mac</family>
</os>
</activation>
<properties>
<catalina.home>...</catalina.home>
</properties>
</profile>
<profile>
<id>path-to-catalina.home-windows</id>
<activation>
<os>
<family>windows</family>
</os>
</activation>
<properties>
<catalina.home>...</catalina.home>
</properties>
</profile>
You could use a profile in your pom that gets activated based on os.
<profiles>
<profile>
<activation>
<os>
...
What are you doing that require catalina.home?
If you're doing deployment to an app server with maven, you are already outside of the 'consistent, portable build' rule set - and outside of the main use case / best practices for maven.
Not that you shouldn't do it - as it's convenient. Just make sure to separate your build projects from the deployment projects.

How to generate two sonar reports from the same project?

I would like to create two sets of Sonar reports from the same project. One would have everything covered and the other one would have some packages excluded.
Is this possible and if so, how to do such?
Edit: Setting exclusions is not a problem but having two reports is.
Create new profile in maven and add call sonar with new branch for each profile: mvn clean install -Pprofile1 sonar:sonar -Dsonar.branch=BRANCH1
<properties>
<sonar.branch>
DEFAULT_BRANCH
</sonar.branch>
</properties>
<profiles>
<profile>
<id>sonar</id>
<activation>
<activeByDefault>true</activeByDefault>
</activation>
<properties>
<sonar.host.url>
http://localhost:9000
</sonar.host.url>
</properties>
</profile>
<profile>
<id>profile1</id>
<properties>
<!-- Optional URL to server. Default value is http://localhost:9000 -->
<sonar.host.url>
http://myserver:9000
</sonar.host.url>
</properties>
</profile>
</profiles>

Confused that order matters when defining conditional profiles in maven

I have a configurable property line.ending that I used during the assembly phase of the building of my project to specify the line ending type of my application property files. For that I have created two profiles LF_DOS and LF_UNIX, so that when I launch :
mvn install
or
mvn install -P LF_DOS
line.ending equals 'dos', and when I launch :
mvn install -P LF_UNIX
line.ending equals 'unix'.
My first attempt to do this was simply :
<profile>
<id>LF_UNIX</id>
<activation>
<activeByDefault>false</activeByDefault>
</activation>
<properties>
<line.ending>unix</line.ending>
</properties>
</profile>
<profile>
<id>LF_DOS</id>
<activation>
<property>
<name>!line.ending</name>
</property>
</activation>
<properties>
<line.ending>dos</line.ending>
</properties>
</profile>
Unfortunately, this always gave me line.ending=dos, whatever LF_UNIX is set or not. Weird... But, the more confusing to me, is that I solved the problem just by changing the profile declaration order, like this :
<profile>
<id>LF_DOS</id>
<activation>
<property>
<name>!line.ending</name>
</property>
</activation>
<properties>
<line.ending>dos</line.ending>
</properties>
</profile>
<profile>
<id>LF_UNIX</id>
<activation>
<activeByDefault>false</activeByDefault>
</activation>
<properties>
<line.ending>unix</line.ending>
</properties>
</profile>
This works exactly like I want.
My questions is : is this a bug ? Or is it something to know about maven profiles, a kind of limitation that makes profiles order declaration particularly matter in such a case ?
The confusion lies in your understanding of how profile activation works.
You think that this:
<activation>
<property>
<name>!line.ending</name>
</property>
</activation>
means if I don't have a maven property named "line.ending" set, activate this profile. What it really means if I didn't specify -Dline.ending=X on the command line, activate this profile. So unless you run something like this:
mvn clean install -Dline.ending=unix
You are activating this profile and thus having the value set to dos.
