Update LogbackLoggingSystem to include status errors in the exception
rather than using `System.err`. Also perform additional cleanup in an
attempt to fix CI build failures.
Fixes gh-3309
Improve the "hints" section of the metadata so that each hint can provide
the reference to a value provider.
A value provider defines how a tool can discover the potential values of
a property based on the context. The provider is identifed by a name and
may have an arbitrary number of parameters.
Closes gh-3303
Update documentation section that discusses uber jars since it conflates
the concepts of the uber jar and the shading of dependencies into jars
(which may or may not be true uber jars).
Fixes gh-3321
Extract common features from CounterBuffers and GuageBuffers into
a shared superclass. The new extracted types allows the service
implementations to be simplified.
Fixes gh-3257
Update EventPublishingRunListener to implement Ordered and use a default
order of 0. This allows for other run listeners to be added either
before or after it.
Fixes gh-3305
Create a new section in the meta-data called "hints" where users can
provide hints about a given property. The most basic use case for now
is to provide a list of values that a property can have. Each value may
have a description.
This sample JSON provides a basic example for a property called `foo.mode`
that exposes 3 values: "auto", "basic" and "advanced".
```
"hints": [
{
"id": "foo.mode",
"values": [
{
"value": "auto",
"description": "Some smart description."
},
{
"name": "basic"
},
{
"name": "advanced"
}
]
}
]
```
This information can be read by tools (such as IDE) and offer an
auto-completion with the list of values.
Closes gh-2054
If java.io.tmpdir is configured to a directory that does not exist,
calls to File.createTempFile will fail with an IOException with the
message "The system cannot find the path specified". Unfortunately,
the path the was specified is not included in the message.
Rather than trying to automatically create the directory in what may
be a misconfigured location, we now include the value of
java.io.tmpdir in our own exception's message. Hopefully this will
help users to figure out what they've done wrong.
Closes gh-3307
Provide a static utility method to get the Spring Boot version based on
the implementation version of SpringApplication's package. Similar to
Spring Frameworks' SpringVersion class.
Fixes gh-2300
Add AnsiPropertySource which allows named ANSI codes to be resolved
and update ResourceBanner to include it.
This commit also deprecates constants defined in AnsiElement and
replaces them with AnsiStyle, AnsiColor and AnsiBackground enums.
Closes gh-2704
