Question

Can anyone say if Apache NetBeans 9.0 support java 11 and if so what are the requirements to make that work?

Prensently I can compile and run java 11 code in NetBeans 9.9 but it is underlined with red and the error message is "cannot find symbol ...".

Below is the pom.xml file I use:

   <?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

How, for example pom-file should be changed?

Answer 1

没有NetBeans 9不支持Java 11（仅支持9和10）[1]。

计划于11月[2]发行的

NetBeans 10将支持Java 11 [3]。不幸的是，它尚不可用（至少是正式版本）。

最新候选版本可以在此处下载

https://dist.apache.org/repos/dist/dev/incubator/netbeans/incubating-netbeans/

由于NetBeans 10最新投票候选人5处于最终发行投票阶段[4]，我们应该期望在未来几天内最终发行。

Answer 2

具有JDK 11支持的NetBeans 10 has been released：

对LVTI的支持对Lamdba参数的支持



新提示可将lambda参数的变量类型转换为'var'（JDK   11及以上）



var lambda参数的代码完成



对var类型lambda参数的代码完成支持。（JDK 11和   以上）



有关更多详细功能，请参见JDK 11 Confluence Page。
