I'm using Redmine 3.4.2, and the latest PlantUML plugin. The PlantUML plugin supports both png and svg format.

However, the png format doesn't work. It shows hex string only. I checked background Redmine log, which shows the generated png file is 0 byte. The svg format works fine.

Finally I got it working by workaround and here is the details, with PlantUML plugin tag v0.5.1.

1. This script works for svg, but not for png.
   Bob -> Alice : hello
2. If I removed space between "Alice" and ":", as well as that between ":" and "hello", png works. This makes me thought svg works but png doesn't work. It looks png needs more strict requirement which should not have space in some specific position. I'm not sure anything wrong on my platform to have such issue.
   Bob -> Alice:hello
3. In plantuml setting, no matter what binary I set, it always works. But if I leave it empty, the plugin doesn't work. I think it checks the binary location, but never use it.
4. This also works, if no space in "Bob->Alice", while keep spaces in "Alice : hello"
   {{plantuml(png)
   Bob->Alice : hello
   }}

Redmine::PluginRequirementError: plantuml plugin requires a Redmine version between 2.6 and 3.3 but current is 3.4.2.stable

For textile syntax is

{{plantuml(png)
  Bob -> Alice : hello
}}

What should be syntax to use within markdown?

I have installed in Redmine 3.1.0 with plantuml on Centos 7
Not working export pdf or html from redmine- wiki.
In redmine->wiki plantuml show works sample:
{{plantuml(png)
Bob -> Alice : hello
}}

But after export in html page source -> example

The same link in export pdf file.
Not showing pictures.

Best regards Konstantins.

If I try to view a saved diagram (=saving text in a wiki to see the results), the following error occours:

undefined method `+' for nil:NilClass

Environment:
Redmine version 3.4.2.stable

RM 4.04 Win10, Ruby 4 Windows with DevKit

Hello,

I've installed the PlantUML plugin for Redmine and everything looks fine.

But I cannot make any State diagram to work. Examples:

[*] --> State1
State1 --> [*]
State1 : this is a string
State1 : this is another string

State1 -> State2
State2 --> [*]

(yes, I used the start and end tags)

The jar versions I've tested are:

plantuml-8059.jar

plantuml.1.2017.16.jar

This is the way I use it:
/usr/bin/java -Djava.io.tmpdir=/var/tmp -Djava.awt.headless=true -jar /var/www/redmine/plugins/plantuml/bin/20171003-plantuml.1.2017.16.jar ${@}

As I said before, every other diagram works fine, but not State diagrams.

Thanks for your help

The plugin does not work "out of the box" on debian system because of Differences from upstream Redmine

Error given is:

Error executing the plantuml macro (No such file or directory @ rb_sysopen - /usr/share/redmine/files/plantuml_[...].pu)

Solution is:

ln -s /var/lib/redmine/default/files/ /usr/share/redmine/files

Hello,

I would like to propose the capability to give the plugin an URL to an external PlantUML Server to add the PlantUML feature to redmine.

This would help preventing redundancy in IT infrastructure.

Here is my script file and output when run:

#!/bin/bash

I've just installed this plugin on redmine 3.2 just fine (changing 3.1 with 3.2 in init.rb). But when installing on 2.6 something going wrong:

I tried the following codes, but it not worked for me.

{{plantuml(png)
  Bob -> Alice : hello
}}

I just got a string : Plantuml 9a38d4b478cf8f704fffa67de88d1d183d141daa7354806a934bbdc815db2362

I am using context : http://localhost/redmine

1. configuration sub context

insert to first line in "config/environment.rb"
`RedmineApp::Application.routes.default_scope = "/redmine"'

2. result

I've installed Java on the ubuntu redmine server, plug-in installed in correct plug-in dir, /usr/bin/plantuml file created and given execute permissions and redmine rake command ran:

bundle exec rake redmine:plugins:migrate RAILS_ENV=production
Migrating plantuml (PlantUML plugin for Redmine)...
...
...
...

but plug-in not appearing in plug-in list and path in the readme file gives a 404 and in fact there is no *.jar file in the downloaded plug-in dir.

Where is config for image caching

in this case http://plantuml.com/sequence-diagram#Splitting_diagrams
{{plantuml(png)
Alice -> Bob : message 1
Alice -> Bob : message 2

newpage

Alice -> Bob : message 3
Alice -> Bob : message 4

newpage A title for the\nlast page

Alice -> Bob : message 5
Alice -> Bob : message 6

}}

the plugin include the first schema only. the 2 others are generated on disk but not included in the issue

best regards

Is there a chance to remove non used files ?

• Maybe give the diagram a name and don't hash the changes.

First of all, thanks for the great plugin!

I would like u to make a case differentiation in the "Installation" section of your readme.

Please add the following batch script example:

java -Djava.io.tmpdir=%TEMP% -Djava.awt.headless=true -jar PATH_TO_YOUR_PLANTUML_BINARY/plantuml.jar "%1" "%2" "%3" "%4"

Using

{{plantuml(svg)
  Bob -> Alice : hello
}}

results in redmine printing the SVG as image. Therefore, e.g. links in the SVG can not be clicked.

Is there a possibility to incorporate this behaviour?
