Fail to build IDE 1.8.8

Hi,
I fail to build the IDE 1.8.8.
I run Debian sid / GNU Linux.
I get the following:
```
/usr/local/src/arduino/arduino-1.8.8/build/ ant dist
Buildfile: /usr/local/src/arduino/arduino-1.8.8/build/build.xml

[echo] latest in package_index_bundled.json is: 1.6.23
[echo] Latest revision detected in shared/revision.txt is: 1.8.7
[echo] Revision in BaseNoGui.java is: 1.8.8

dist:
