java home configuration in maven
Hi, I have a problem with the java home configuration when I work with Netbeans 10 (but I guess that also other versions are affected).
- In my company we still use JDK 8 so I configured the JAVA_HOME system variable to point to the JDK 8 folder. This configuration seems correct, I can see from the prompt that typing java -version the correct version of java is taken in account.
- NetBeans 10 "requires" (prefers) Java 11 so I downloaded the OpenJDK11, extracted it on a folder and configured the path on the netbeans.conf file (netbeans_jdkhome="D:\java\jdk11") also this configuration seems to be ok.
- One of the maven project on which I'm working (remind we use java 8) has an external dependency like this:
<dependency>
<groupId>com.sun</groupId>
<artifactId>tools</artifactId>
<version>${jdk.version}</version>
<scope>system</scope>
<systemPath>${java.home}/../lib/tools.jar</systemPath>
</dependency>
The problem is that ${java.home} is translated using the netbeans_jdkhome path and not the system JAVA_HOME variable so it points to jdk 11 and not jdk 8 and it doesn't find the path.
In Netbeans Java Platform Manager I have both the java version jdk 8 and jdk 11(default) but the default version can't be changed.
How can I workaround this limitation so that I can work on the maven project using the jdk 8 home?
Kind regards,

In Project Properties | Build | Compile you can configure the 'Java
Platform' for the project. I see that switching to Java 8 makes the
compilation work for me:
cd /Users/apache/CoolBeansProjects/deleletmeee;
JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home
"/Users/apache/work/coolbeans/CoolBeans-2018.12-20190110-235217/CoolBeans/CoolBeans
2018.12.app/Contents/Resources/coolbeans/java/maven/bin/mvn" clean
install
<dependencies>
<dependency>
<groupId>com.sun</groupId>
<artifactId>tools</artifactId>
<version>1.8</version>
<scope>system</scope>
<systemPath>${java.home}/../lib/tools.jar</systemPath>
</dependency>
</dependencies>
OTOH, using the default Java 10 breaks the build:
cd /Users/apache/CoolBeansProjects/deleletmeee;
"JAVA_HOME=/Users/apache/work/coolbeans/CoolBeans-2018.12-20190110-235217/CoolBeans/CoolBeans
2018.12.app/Contents/Resources/coolbeans/jre"
"/Users/apache/work/coolbeans/CoolBeans-2018.12-20190110-235217/CoolBeans/CoolBeans
2018.12.app/Contents/Resources/coolbeans/java/maven/bin/mvn" clean
install
Failed to execute goal on project deleletmeee: Could not resolve
dependencies for project com.mycompany:deleletmeee:jar:1.0-SNAPSHOT:
Could not find artifact com.sun:tools:jar:1.8 at specified path
/Users/apache/work/coolbeans/CoolBeans-2018.12-20190110-235217/CoolBeans/CoolBeans
2018.12.app/Contents/Resources/coolbeans/jre/../lib/tools.jar -> [Help
1]
So the only remaining issue is that, indeed, you cannot globally
change the default Java Platform from Tools | Java Platforms.

No, it does not. It runs on JDK 8 or above, to the current JDK, which is
JDK 11.
