I use maven to build my project.
I have following configuration:
D:\freelance\polyndrom>mvn -verion Apache Maven 3.2.3 (33f8c3e1027c3ddde99d3cdebad2656a31e8fdf4; 2014-08-12T00:58:1 0+04:00) Maven home: C:\Program Files\apache\apache-maven-3.2.3 Java version: 1.8.0_25, vendor: Oracle Corporation Java home: C:\Program Files\Java\jdk1.8.0_25\jre Default locale: ru_RU, platform encoding: Cp1251 OS name: "windows 7", version: "6.1", arch: "amd64", family: "dos"
but when I compile project I see following errors:
lambda expressions are not supported in -source 1.5
I am confused - mven sees that I use java 8.

By default, Maven assumes you wrote your code using JDK 1.5 and that you want to compile to that same target. You will need to add the maven-compiler-plugin to your build plugins, in order to tell it to use 1.8.
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.3</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
</configuration>
</plugin>
</plugins>
</build>
Check out the plugin's docs for more info: http://maven.apache.org/plugins/maven-compiler-plugin/compile-mojo.html
You can specify language version in properties section in pom.xml
file.
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>
