Path to tools.jar in maven on Mac wrong

Question

In my Maven build I have a dependency on the tools.jar;

<dependency>
    <groupId>com.sun</groupId>
    <artifactId>tools</artifactId>
    <version>1.8.0</version>
    <scope>system</scope>
    <systemPath>${toolsjar}</systemPath>
</dependency>

where the toolsjar is defined as a property:

<toolsjar>${java.home}/../lib/tools.jar</toolsjar>

This all works well on Linux and Windows systems. However on a Mac the path is not properly resolved:

java.home:               /Library/Java/JavaVirtualMachines/jdk1.8.0_152.jdk/Contents/Home/jre
resolved property value: /Library/Java/JavaVirtualMachines/jdk1.8.0_152.jdk/Contents/Home/jre/lib/tools.jar
actual location:         /Library/Java/JavaVirtualMachines/jdk1.8.0_152.jdk/Contents/Home/lib/tools.jar

As you can see the tools.jar is searched in the lib folder of the jre instead of the jdk. However the path is properly specified.

Any idea why this does not work as expected, or how to fix it?

Probably your java.home on the mac machine is set to a wrong place. You can change it the same way as on linux - export JAVA_HOME=..... — Veselin Davidov, Oct 26 '17 at 09:47

@VeselinDavidov: The `JAVA_HOME` env variable is not set in either system and `mvn -version` shows me that Linux and Mac point to the JRE as Java Home. — hotzst, Oct 26 '17 at 09:57
There's JAVA_HOME, the environment variable, and java.home, the maven property: https://stackoverflow.com/a/15279640/148680 — chb, Oct 26 '17 at 10:03
@ThorbjørnRavnAndersen I need the compiler API from the tools.jar — hotzst, Oct 26 '17 at 11:40
@hotzst Ok. It does not appear to be in a standard maven repository. Please note that Java 9 moves things around, so you'll need to revisit this later. — Thorbjørn Ravn Andersen, Oct 26 '17 at 14:45
