Question

I\'ve been working with a co-worker on a problem I have been experiencing on a new project I just joined. Long story short, maven isn\'t building my .war file correctly. W

Answer 1

In Eclipse, Window>Preferences>Java>Installed JREs> make sure jdk is present and selected.

If jdk and jre both are present, then delete jre from Installed JREs.

You can modify it on this window:

Answer 3

You can replace the environment from jre to jdk in Eclipse IDE as follows if it also shows compiler unavailable :

• (right-click) your_project_name > Build Path > Configure Build Path > Libraries > (double-click) JRE System Libraries > Alternate Jre : jdk 1.8 >ok
• Then from Installed JRES option in Libraries select jdk 1.8
• Project > Clean
• Maven > Update

Answer 4

From the Maven Properties Guide:

${java.home} specifies the path to the current JRE_HOME environment use with relative paths to get for example: ${java.home}../bin/java.exe

java.home property is not the same thing as JAVA_HOME environment setting. It is actually dynamic property showing you which JRE is running your code. 

Try setting the java.home property correctly and see if it works.

Answer 5

This error also occurs, if you have variable named as javapath. Try to delete it, if you've already specified e.g. like JAVA_HOME -> "C:\Program Files\Java\jdk1.8.0_171" and then in Path -> "%JAVA_HOME%\bin"

Answer 6

Windows CMD don't refresh environment variables and you need run new instance for applying new environment setting and refresh new variable JAVA_HOME.
