Migration from older tools

This section describes how to migrate packages that use older deprecated tools to current ones.

%add_maven_depmap macro

%add_maven_depmap macro was used to manually install Maven artifacts that were built with Apache Ant or mvn-rpmbuild. It is now deprecated and its invocations should be replaced with %mvn_artifact and %mvn_install.

Artifact files, Maven POM files and their installation directories no longer need to be manually installed, since that is done during run of %mvn_install. The installed files also don’t need to be explicitly enumerated in %files section. Generated file .mfiles should be used instead.

Relevant parts of specfile using %add_maven_depmap:

BuildRequires:  javapackages-tools

Requires:       some-library
...

%build
ant test

%install
install -d -m 755 $RPM_BUILD_ROOT%{_javadir}
install -m 644 target/%{name}.jar $RPM_BUILD_ROOT%{_javadir}/%{name}.jar

install -d -m 755 $RPM_BUILD_ROOT%{_mavenpomdir}
install -m 644 %{name}.pom $RPM_BUILD_ROOT/%{_mavenpomdir}/JPP-%{name}.pom

# Note that the following call is equivalent to invoking the macro
# without any parameters
%add_maven_depmap JPP-%{name}.pom %{name}.jar

# javadoc
install -d -m 755 $RPM_BUILD_ROOT%{_javadocdir}/%{name}
cp -pr api/* $RPM_BUILD_ROOT%{_javadocdir}/%{name}

%files
%{_javadir}/*
%{_mavenpomdir}/*
%{_mavendepmapfragdir}/*

%files javadoc
%doc %{_javadocdir}/%{name}

The same specfile migrated to %mvn_artifact and %mvn_install:

# mvn_* macros are located in javapackages-local package
BuildRequires:  javapackages-local

# Since XMvn generates requires automatically, it is no longer needed
# nor recommended to specify manual Requires tags, unless the dependency
# information in the POM is incomplete or you need to depend on non-java
# packages
...

%prep
# The default location for installing JAR files is %{_javadir}/%{name}/
# Because our original specfile put the JAR directly to %{_javadir}, we
# want to override this behavior. The folowing call tells XMvn to
# install the groupId:artifactId artifact as %{_javadir}/%{name}.jar
%mvn_file groupId:artifactId %{name}

%build
ant test

# Tell XMvn which artifact belongs to which POM
%mvn_artifact %{name}.pom target/%{name}.jar

%install
# It is not necessary to install directories and artifacts manually,
# mvn_install will take care of it

# Optionally use -J parameter to specify path to directory with built
# javadoc
%mvn_install -J api

# Use autogenerated .mfiles file instead of specifying individual files
%files -f .mfiles
%files javadoc -f .mfiles-javadoc
Aliases and subpackages

%add_maven_depmap had -a switch to specify artifact aliases and -f switch to support splitting artifacts across multiple subpackages. To achieve the same things with %mvn_* macros, see [_additional_mappings] and [_assignment_of_the_maven_artifacts_to_the_subpackages].

If the project consists of multiple artifacts and parent POMs are among them, call %mvn_artifact on these parent POMs first.
