------------------------------
Summary: Compilation error for build from source (Ubuntu 17.10,
Java 8, Ant 10.2)
Key: NETBEANS-449
URL: https://issues.apache.org/jira/browse/NETBEANS-449
Project: NetBeans
Issue Type: Bug
Environment: Ubuntu 17.10, Java 8u151, Ant 1.10.2
Reporter: Kevin
Attachments: installing-apache-netbeans.log
I failed to build incubator Apache NetBeans from source. I cloned the master
branch, ran ant v10.2 with Java 8u151 installed. It broke on a Java compilation
error:
{code:java}
bootstrap:
[echo] Bootstrapping NetBeans-specific Ant extensions...
[javac] Compiling 53 source files to
/media/kevvurs/ExtraDrive1/incubator-netbeans/nbbuild/build/antclasses
[javac]
/media/kevvurs/ExtraDrive1/incubator-netbeans/nbbuild/antsrc/org/netbeans/nbbuild/LayerIndex.java:344:
error: class ZipArray inherits unrelated defaults for stream() from types
ResourceCollection and Collection
[javac] private static final class ZipArray extends ArrayList<Resource>
[javac] ^
[javac] 1 error
{code}
ZipArray extended ArrayList and implemented ResourceCollection, so Java broke
on the multiple stream() definitions. I am guessing Java 9 would get around
this, but the documentation says it will work with Java 8.
